Determine the volume of gas obtained by the action of an excess of sulfuric acid 150 g of sodium carbonate.

When sulfuric acid and sodium carbonate interact, an unstable carbonic (carboxylic) acid is formed, which decomposes into water and carbon dioxide. It is this gas that is released as a result of the reaction.

The equation for this reaction is as follows:

Na2CO3 + H2SO4 = Na2SO4 + H2O + CO2

The molar mass of sodium carbonate is 106 g / mol; the molar volume of carbon dioxide is 22.4 l / mol (according to Avogadro’s law)

Let’s make a proportion according to the reaction equation:

150 g of sodium carbonate corresponds to X l. carbon dioxide like

106 g / mol sodium carbonate corresponds to 22.4 l / mol carbon dioxide

X = (150 * 22.4) / 106 = 31.7 liters.

Answer: gas volume 31.7 liters
