Question

when concentrated acid is added to water whether the process is exothermic or endothermic

Answer 1

Answer: exothermic

Explanation: Exothermic processes are those processes in which heat is released and endothermic processes are those processes in which heat is absorbed.

When acid is added to water, heat is released when high energy bonds are broken and form newer lower energy bonds.

When concentrated acid is added to water, the strong bonds of acid are broken and they dissociate in to ions, thus releasing a large amount of energy in the form of heat.

$HA\rightarrow H^++A^-$
