How much carbon dioxide will be released when 100 g of sodium carbonate interacts with hydrochloric acid?

The reaction of sodium carbonate dissolution in hydrochloric acid is described by the following chemical reaction equation:

Na2CO3 + 2HCl = 2NaCl + CO2 + H2O;

When 1 mol of sodium carbonate is dissolved in acid, 1 mol of gaseous carbon dioxide is synthesized. This consumes 2 mol of hydrochloric acid.

Let’s calculate the chemical amount of a substance contained in 10.6 grams of sodium carbonate.

M Na2CO3 = 23 x 2 + 12 + 16 x 3 = 106 grams / mol;

N Na2CO3 = 100/106 = 0.943 mol;

Thus, when 0.943 mol of soda is dissolved, 0.943 mol of carbon dioxide is synthesized.

Let’s calculate its volume. To do this, multiply the amount of the substance and the standard volume of 1 mole of the gaseous substance. 1 mole of ideal gas fills a volume of 22.4 liters under normal conditions.

V CO2 = 0.943 x 22.4 = 21.123 liters;
