The determinant is the mass of the salt formed by neutralizing a solution
The determinant is the mass of the salt formed by neutralizing a solution containing 9.8 g of sulfuric acid with an excess of barium hydroxide.
Barium hydroxide reacts with sulfuric acid. At the same time, a water-insoluble barium sulfate salt is synthesized, which precipitates. The reaction is described by the following chemical reaction equation.
Ba (OH) 2 + H2SO4 = BaSO4 + 2H2O;
Barium hydroxide 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 = 9.8 / 98 = 0.1 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 = 0.1 x 233 = 23.3 grams;
