$13 on ebay bought me a USB powdered salt to sodium hydroxide converter. Great because with no mains water, and plenty of salt I had bought for food preserving, I can now have chlorine to sterilise things.

Awesome channel, easy sub. I like your resourcing and creativity as well as your details on your process. 😁 Thanks for sharing :)

To test for presence of NaOH - create a solution of the crystal, and drop in a little bit of aluminum foil. If you get bubbles forming at the foil, this confirms the presence of NaOH. The bubbles are hydrogen. The reddening of the tumeric only confirms alkinity, not necessarily presence of NaOH

@@meteozgan4066 it's going to vary depending on voltage, as well as the total current and time relative to concentration. If you expel all of the chlorine, you can be reasonably certain you're not getting hypochlorite

Providing the gases escape (are vented) you will produce sodium hydroxide in the solution. If the gases coming from the cathode and the anode have a chance to recombine they will combine to produce hydrochloric acid. If the acid comes into contact with the solution it will combine with the forming sodium hydroxide to produce salt (sodium chloride).

thanks

how will you purify the sodium hydroxide?

Sir, I have a question. I electrolyzed sodium salt while anode and catode in the same container. Then, when the electrolysis process was completed, I filtered it. I don't have a chance to do a Ph test, but I threw aluminum into the liquid I produced, the moment I threw it into it, bubbles started to appear, and its very visible then I lit the lighter. and even though the lighter was 2-3 cm away from the aluminum, a crackling sound started to come out of. The flame of the lighter become more orange than normal, but i can say color of the lighter fire has clearly changed. What do you think sir the chemical I produced? Is it sodium hydroxide or sodium hypochlorite?

Sounds like you have just burnt of hydrogen gas. That’s what is also produced from this reaction. Especially after you have added a piece of aluminium to the mixture! Make sure you vent the gas. I would be cautious with an open flame around it as well. Here’s why. In 2014 I completed a similar experiment. But I enclosed the liquid in a bottle and then I added the piece of aluminium foil into the bottle and tightened the lid. Over the next few hours the aluminium bubbled and fizzed and the bottle become tighter and tighter. The next day I decided to do the same test. So I removed the lid to the bottle and put a flame to the gases that were escaping from the bottle. Boom! White hot flames could be heard howling out of the bottle. They could be barely be seen. And there were sparks of orange as you had just described. You need to be real careful not to burn yourself.

Hi. Hope all is well. If the electrolysis is completed in one beaker only (not in a h cell) than providing the gases that are released (hydrogen and chlorine) can escape, than sodium hydroxide will be produced in the solution. If the gases cannot escape than hydrochloric acid will form above the solution (from the chlorine gas and hydrogen gas combining) and than will than run back into the beaker and recombine with the sodium hydroxide to create salt again. I hope this helps!

Could you please tell me what is produced in the positive side.

Does soda heat up after dissolving the caustic to water?

Yep, caustic soda will cause an exothermic reaction when added to water. Be sure to add the soda to the water. Not the other way around.

Why did you make the electrodes so long that they come into direct contact with the precipitate?

Only just seen your comment. Sorry for the late reply. The reason I made them so long was because I am Jerry rigging this experiment as I go! I’m still learning. Cheers!

You know that by leaving it out in the open air it absorbs carbon dioxide and turns into sodium carbonate? Check the small amount with some vinegar if any bubbles, the bubbles are from the carbonate, also do the aluminum test that someone else recommended, if it doesn't react and make bubbles, then it's all carbonate! You probably got a mixture and I have no idea how to tell you how to figure out accurately the ratio..

Why did you put those steel metal rods together with carbon rods

@Remraf

Жыл бұрын

That is a good question. The only answer is that I was under the assumption that with more surface area I would be able to perform quicker electrolysis. And the carbon electrodes were already available to use so I decided to keep them.

Maybe you could test it by adding aluminum foil to a concentrated solution of the salt you made and see if it starts bubbling and producing hydrogen.

Sounds like an awesome idea! About 6 years ago I created a similar mixture from mixing potassium carbonate and calcium hydroxide to produce potassium hydroxide. I then added strips of aluminium to the solution in a coke bottle. Thinking that it did not work I decided to light the mix up. Big mistake. I almost blew by fingers off. The heat and sparks that escaped were similar to that of a blow torch! Can’t wait to try again! Stay tune for a video. I will see if I can knock it out tomorrow. Thanks for the suggestion!

there is no problem for steel being the cathode. I have experienced this myself. The only problem is the pesky anode being oxidized over and over again. In order to solve this I used graphite from graphite pencils. Under such conditions especially in aqeous solutions there is no problem for using graphite as the anode. Graphite is relatively an inert material and being an amateur chemist myself I can say this that using graphite or nickle oxide or even better platinum as our anode no problem should be occuring. With my graphite electrode as the anode I did not see any visible corrosion on the anode aboviously as graphite is inert but due to the Chlorine gas or Cl2 forming the water will still turn yellowish greenish due to the formation of hypochlorous acid (a byproduct of the Cl2 reacting with the water) and when it dissolves into water it can cause a bit of a greenish and a yellowish color

@Remraf

@meteozgan4066 here are some details. I hope this helps. Cheers! To perform electrolysis of salt water (sodium chloride solution), you need to consider both the concentration of the salt solution and the power supply. In your case, you have a 12-volt, 3-ampere power source and a solution made from 200 ml of water and 50 grams of NaCl (sodium chloride). 1. **Concentration of the Solution**: Your solution has 50 grams of NaCl in 200 ml of water. This is a relatively high concentration, which is typically good for electrolysis as it ensures sufficient ions are available for the reaction. 2. **Power Source**: The 12V, 3A power supply is generally sufficient for small-scale electrolysis. The key factors here are voltage and current. The voltage (12V) is enough to cause the electrolysis of water. The current (3A) determines the rate at which the reaction will happen. 3. **Duration of Electrolysis**: Calculating the exact time needed to complete electrolysis is complex because it depends on various factors such as the efficiency of your setup, the surface area of the electrodes, and the specific conditions of the electrolysis (like temperature). In general, the amount of gas produced (hydrogen and oxygen) can be calculated using Faraday's laws of electrolysis. However, for a complete reaction in a practical setting, it's usually more of a trial-and-error process, especially for small-scale, non-industrial electrolysis. 4. **Safety Note**: Electrolysis of salt water produces chlorine gas at the anode and hydrogen gas at the cathode, along with sodium hydroxide in the solution. Chlorine gas is dangerous, and hydrogen is highly flammable. It's crucial to perform this experiment in a well-ventilated area and take appropriate safety precautions. Remember, this is a simplified overview, and the actual results can vary based on your experimental setup. If you need a more precise calculation or further advice, you might want to consult with a chemistry professional or use more advanced tools to measure the progress of your electrolysis.

Evaporation of the water will occur with both heat and light. This was for some time debatable on this channel. The current consensus says that both heat and the light from the sun/lights will evaporate the water. The electrolysis process will as well. The time it will take will depend of the amount of energy being put into the process as well as its location. This is a tough one to give you a direct answer on as there are many variables to take into account to account. And each variable will impact the evaporation time.
