Write a balanced equation for the double-replacement neutralization reaction described, using the smallest possible integer coefficients. a reaction occurs when aqueous solutions of phosphoric acid and potassium hydroxide are combined. assume excess base.

The chemical reaction is given below.

Explanation:

Double displacement reactions are defined as the reactions in which exchange of ions takes place. The general equation for this reaction follows:

The chemical equation for the reaction of phosphoric acid and potassium hydroxide follows:

By stoichiometry of the reaction:

1 mole of phosphoric acid reacts with 3 moles of potassium hydroxide to produce 1 mole of potassium phosphate and 3 moles of water.

This is also known as neutralization reaction.
