What mass of sediment can be obtained as a result of the exchange reaction between an excess

What mass of sediment can be obtained as a result of the exchange reaction between an excess of barium chloride solution and 196 g of sulfuric acid solution with a mass fraction of 15%?

Barium chloride salt reacts with sulfuric acid. In this case, a water-insoluble barium sulfate salt is formed, which turns into an insoluble precipitate. The reaction is described by the following chemical reaction equation.

BaCl2 + H2SO4 = BaSO4 + 2HCl;

Barium chloride reacts with sulfuric acid in equal molar amounts. In this case, the same amount of insoluble salt is synthesized.

Let’s calculate the chemical amount of sulfuric acid.

M H2SO4 = 2 + 32 + 16 x 4 = 98 grams / mol; N H2SO4 = 196 x 0.15 / 98 = 0.3 mol;

Barium sulfate will be synthesized in the same molar amount.

Let’s find its weight.

M BaSO4 = 137 + 32 + 16 x 4 = 233 grams / mol; m BaSO4 = 0.3 x 233 = 69.9 grams
