To produce sodium sulfate by the reaction illustrated you need ...?
1. sodium chloride + sulfuric acid
2. potassium sulfate + sodium hydroxide
3. sodium hydroxide + hydrochloric acid
4. sodium hydroxide + sulfuric acid
The answer is 1. Sodium sulfate can be produced by reacting sodium chloride with sulfuric acid. This reaction yields sodium sulfate and hydrochloric acid as products. The balanced chemical equation is:
2 NaCl + H2SO4 -> Na2SO4 + 2 HCl
