Answer:
Hello, Im Mack. Hope your doing well :)
Here is the Correct answer to your question:
Step-by-step explanation:
-Exothermic means that the reaction produces heat.
-Dissolving the crystal in water should be endothermic - requiring to heat to produce.
(The temperature of the water should decrease) ->-The dissociation could still occur if the crystals are hydrophilic and the pH of the solution is appropriate to promote solubility.
Hope this helped you :)
