A student observed that the temperature of water

increased when a salt was dissolved in it. The

student should conclude that dissolving the salt

caused

A.

formation of an acidic solution

B.

formation of a basic solution

C.

an exothermic reaction

D. an endothermic reaction

Increasing temperature increases the solubility of most salts, but not all. The reason for the differences is that dissolution involves three steps: breaking bonds of salt in the lattice; forming cavities in water the same size as the ions; interacting the salt with water in the cavity.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
