Glad you liked it!

Ha! I actually found this video I can’t believe it. Ive been thinking about this experiment all day. Hope you are doing well mr.moverman :)

I think you are the first person that I know to have commented on my channel! I hope that you are doing well too. I also hope that you had a good first semester. Thanks for watching!

Wow this is actually really interesting, will try to replicate some of it for my science fair project. However, how long does this experiment usually take?

You can do it pretty much in a day. A lot of it is just waiting around. Especially when you do the redox reactions. Let me know how it goes!

What makes the solution bubble when you put the metal in it?

Some hydrogen gas is produced during the process.

Is that copper chloride solution or copper sulfate solution because both are blue

Hi Lea, because the pennies were soaking in vinegar( dilute acidic acid), the dissolved compound is copper acetate. There are also chloride ions from the salt. However, the negative ion isn’t so important because the blue color comes from the positive copper ions. So you get the same color whether the negative ion is acetate, chloride, sulfate, or nitrate.

@@mmoverman ok thank u 🥰

We tried the experiment in lab and we did not get enough copper (II) ion to turn the solution blue or react with the aluminum. How many times did you soak your pennies?

Hard to remember since it's been a while but probably at least five or six times. I found that the pennies became more effective each time I ran them through the cycle. So if you are starting with new pennies it could take a while to get them "conditioned." Starting with old tarnished pennies probably would be more efficient. Ultimately, keep cycling until you get the desired concentration of blue that you want. Then hold onto the pennies for next year!

By the way, the fact that you have to attend to the experiment for a few minutes every 1-3 hours or so for most of the day is why it's a "do at home" experiment. It's definitely not suited to a single lab. Though if you start with pre-conditioned pennies, i.e. run them through the cycle many times before they are used in class, it could go a lot faster.

How can I do the rinsed and unrinsed paper

I'm not sure I understand your question. Can you try again?
