SODIUM HYDROXIDE DISSOCIATES COMPLETELY IN WATER TO YIELD MORE HYDROXIDE IONS IN SOLUTION THAN HYDROGEN IONS RESULTS IN EXOTHERMIC REACTION.
Explanation:
A strong electrolyte dissociates completely into ions in aqueous solution. When sodium hydroxide, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.
NaOH(s) --> Na+(aq) + OH-(aq)
We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.
It comes under Exothermic reaction as heat gets released.
A solution where in water is the dissolving medium or solvent, is a type of homogenous mixture in which the particles of one or more substances are distributed uniformly throughout another substance.
It is comprised basically of a dissolving agent called solvent and the dissolving material called the solute.
