When zinc interacted with a sulfuric acid solution, 44.8 liters were released. hydrogen. How much zinc and acid have reacted?

One of the most common methods for producing hydrogen in the laboratory is the method of dissolving zinc in sulfuric acid.

Zn + H2SO4 → ZnSO4 + H2;

The chemical amount of synthesized hydrogen gas will be equal to the amount of zinc reacted.

Let’s find the chemical amount of this gas:

N H2 = 44.8 / 22.4 = 2 mol;

To obtain such an amount of hydrogen, it is necessary to dissolve 2 mol of metal in 2 mol of acid.

Let’s calculate the weights of the reacted metal and acid.

The weight of the metal will be equal to:

M Zn = 65 grams / mol;

m Zn = 2 x 65 = 130 grams;

The weight of the sulfate acid will be:

M H2SO4 = 2 + 32 + 16 x 4 = 98 grams / mol;

m H2SO4 = 2 x 98 = 196 grams;
