Sodium hydroxide dissociates completely in water to yield more hydroxide ions in solution than hydrogen ions. This substance would fall under which definition?

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.
