Question

Potassium hydroxide reacts with phosphoric acid (H3PO4) to form potassium phosphate and water. In the balanced chemical equation for this change, what are the lowest, whole number coefficients? Match the number to the substance.

Answer 1

The balanced chemical equation is given as:

`3KOH(aq)+H_3PO_4(aq)\rightarrow K_3PO_4(aq)+3H_2O(l)`

Step-by-step explanation:

When potassium hydroxide reacts with phosphoric acid it gives potassium phosphate and water as a products.

The balanced chemical equation is given as:

`3KOH(aq)+H_3PO_4(aq)\rightarrow K_3PO_4(aq)+3H_2O(l)`

According to reaction, 3 moles of potassium hydroxide recats with 1 mole of phosphoric acid to give 1 mole of potassium phosphate and 3 moles of water.
