Aqueous solutions of potassium hydroxide (KOH) and phosphoric acid (H3PO4) will react to yield potassium phosphate and water. In the balanced equation for this reaction, what is the lowest possible whole number coefficient for water?

Respuesta :

Answer:

3

Explanation:

The reaction is given as;

H3PO4 +  KOH → K3PO4 +  H2O

Upon balancing the reaction, we have;

H3PO4 + 3 KOH → K3PO4 + 3 H2O

The lowest possible whole number coefficient for water (H2O) is 3.
