Exothermic and endothermic dissolution | Solubility | Chemistry

Dissolution of substances in water sometimes involves exchange of heat. In this video 3 compounds sodium hydroxide, ammonium nitrate and sodium chloride are dissolved in water. The temperatures of the solutions are noted after each dissolution. The sodium hydroxide dissolves with release of heat making it an exothermic dissolution. The ammonium nitrate dissolves by absorbing heat; an endothermic dissolution. Only the sodium chloride dissolves with a marginal change of temperature.

This was exactly what I was searching for....❤😊

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.

Exactly what I was looking for... thanks

It's very understandable 😎😎😎 thank making this video

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

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

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?

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?

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

I have a question!

Can Ammonium Nitrate solution be used in a heat exchanger?

Lemme know what happens when Ammonium Nitrate solution is heated.
