Question

How many water molecules are produced in the complete neutralization of one mole of phosphoric acid with potassium hydroxide

Answer 1

Answer: Three (3) molecules of water (H2O)

Step-by-step explanation:

Phosphoric acid = H3PO4

Potassium hydroxide = KOH

Chemical equation is as follows:

H3PO4 + 2KOH --> K2HPO4 + 2H2O (incomplete neutralization yields 2 molecules of water)

K2HPO4 + KOH --> K3PO4 + H2O (complete neutralization 1 molecule of water)

Total water molecules released is 3
