Question

is the dissolution always an endothermic reaction????​

Answer 1

Answer:

The process of dissolving can be endothermic (temperature goes down) or exothermic (temperature goes up). ... If it takes less energy to separate the particles of the solute than is released when the water molecules bond to the particles, then the temperature goes up (exothermic).

Explanation:

Answer 2

Answer:

Explanation:

In dissolution, solute dissolves in the solvent

without reacting chemically with it. In chemical

reaction, reactants will react chemically with

each other and new products are formed. The

bonds in the reactants are broken and new bonds

are formed.
