Question

Sodium chloride reacts with phosphoric acid to form sodium phosphate and hydrochloric acid.

Answer in a balanced chemical equation.

Answer 1

3NaCl + H₃PO₄ → Na₃PO₄ + 3HCl

Step-by-step explanation:

The reactants in this reaction are:

Sodium chloride - NaCl

Phosphoric acid - H₃PO₄

Products of the reaction:

Sodium phosphate - Na₃PO₄

Hydrochloric acid - HCl

Therefore;

NaCl + H₃PO₄ → Na₃PO₄ + HCl

To balance this reaction expression, assign variables a,b, c and d to it;

aNaCl + bH₃PO₄ → cNa₃PO₄ + dHCl

Conserving Na; a = 3c

Cl; a = d

H; 3b = d

P; b = c

O; 4b = 4c

let c = 1, b = 1, a = 3 and d = 3

So;

3NaCl + H₃PO₄ → Na₃PO₄ + 3HCl
