Calculate the mass of the precipitate that forms when sulfuric acid interacts with 300 g of a 15% barium chloride solution
July 3, 2021 | education
| The reaction between sulfuric acid and barium chloride is described by the following chemical reaction equation:
BaCl2 + H2SO4 = BaSO4 + 2HCl;
In the interaction of 1 mol of barium chloride and 1 mol of sulfuric acid, 1 mol of insoluble barium sulfate is synthesized.
Let’s calculate the chemical amount of a substance that is contained in 300 grams of a 15% barium chloride solution.
M BaCl2 = 137 + 35.5 x 2 = 208 grams / mol;
N BaCl2 = 300 x 0.15 / 208 = 0.216 mol;
The same amount of barium sulfate will be synthesized.
Let’s calculate its weight.
M BaSO4 = 137 + 32 + 16 x 4 = 233 grams / mol;
m BaSO4 = 233 x 0.216 = 50.328 grams;
