Calculate the mass of the precipitate that formed during the interaction of solutions containing, respectively, barium nitrate with a mass of 26.1 g and sulfuric acid with a mass of 4.5 g.
The reaction between sulfuric acid and barium nitrate is described by the following chemical reaction equation:
Ba (NO3) 2 + H2SO4 = BaSO4 + 2HNO3;
When 1 mol of barium nitrate and 1 mol of sodium sulfuric acid interact, 1 mol of insoluble barium sulfate is synthesized.
Let’s calculate the chemical amount of a substance that is contained in 4.5 grams of sulfuric acid.
M H2SO4 = 2 + 32 + 16 x 4 = 98 grams / mol;
N H2SO4 = 4.5 / 98 = 0.046 mol;
Let’s calculate the chemical amount of a substance that is contained in 26.1 grams of barium nitrate.
M Ba (NO3) 2 = 137 + (14 + 16 x 3) x 2 = 261 grams / mol;
N Ba (NO3) 2 = 26.1 / 261 = 0.1 mol;
Thus, not more than 0.046 mol 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 0.046 = 10.72 grams;
