concept clear🥳🥳🥳

this was helpful. Thankyou!

so nice continue so helpful

Regarding Temperature Swing Solvent Extraction and using waste heat to recharge calcium nitrate for a cooling application. If you take a water and calcium nitrate solution and mix it with an amine (more then 6 carbons so it is not miscible) that will take up the calcium nitrate at elevated temperatures but not hold it at lower temperatures what would the likely outcome be if water and the amine are mixed at a lower temperature? When the calcium nitrate goes into the water solution from the amine solution is it this likely this will cause the temperature to drop further?

Exactly what I was looking for... thanks

It's very understandable 😎😎😎 thank you......for making this video

While measuring temperature, the thermometer is not supposed to touch the base of the beaker. It is only supposed to be immersed in the solution.

Tell about Ammonium nitrate

Very nice 😱😱😱

Why is dissolving salt in water exo or endothermic? Is it because of breaking bonds?

This still doesnt answer my question on regards what makes the reaction endo or exo. I understand temp increase, is exo as heat is released from the system(salt) to the surrounding(water) while temp. decrease is vice versa. What makes the ionic salt to be exo or endo? In this reaction, it undergoes two process which is lattice dissociation and hydration. Factors increase lattice dissociation is its size and charge. Both have positive correlation. Meanwhile for hydration reaction, an increase includes the factors size and charge which charge is the same a positive while size a negative; Li ion has a higher hydration energy than K ion. So im basically stuck here. Anyone? Help?

Li has higher energy than K cos hydration energy depends upon size and amount of charge..Smaller the size higher will be the Hydration energy and higher the charge higher will H.E.Li have both small size and high charge as compare to K

Nice

Anyone up for using gloves with a high molarity sodium hydroxide solution?

I could be understand very easy

​@omarismail54No need to say that, mate

why doesn't anyone explains why some dissolutions are exothermic and some are endothermic??

It's a tug-of-war between the salt atoms keeping themselves together and the water molecules trying to pull them apart. If the water molecules aren't quite strong enough they need help from heat in the environment to rip apart the salt making it endothermic

I have a question! Can Ammonium Nitrate solution be used in a heat exchanger? Lemme know what happens when Ammonium Nitrate solution is heated.

Ammonium nitrate salt(solid) disintegrates to nitrous oxide and water upon heating, though, if it is an aqueous solution, I guess nothing would happen
