Answer to Question #260982 in General Chemistry for Tori

Question

Sodium carbonate reacts with hydrochloric acid to form sodium chloride, water and carbon dioxide.

A student mixed some sodium carbonate with an excess of hydrochloric acid in a beaker. The reaction mixture lost mass, due to 700 mL of carbon dioxide gas escaping.

If the student evaporated the mixture to obtain sodium chloride crystals, what mass of NaCl(s) would they obtain? (The procedure was carried out under SLC and 100% yield was obtained).

Include the balanced equation in the first line.

Answer 1

The word equation for the reaction is: solid sodium carbonate reacts with hydrochloric acid solution to produce water, sodium chloride in solution, and carbon dioxide gas.

When dilute hydrochloric acid reacts with sodium carbonate, then sodium chloride, carbon dioxide and water are formed. A brisk effervescence is seen in the release of carbon dioxide.

Na2CO3 + 2 HCl → 2 NaCl + H2CO3
