When dissolved in acetic acid, metallic zinc is converted to zinc acetate. The reaction is described by the following chemical reaction equation:
Zn + 2CH3COOH = Zn (CH3COO) 2 + H2;
Let’s find the chemical amount of zinc. To do this, we divide its weight by the mass of 1 mole of metal.
N Zn = 130/65 = 2 mol;
With this amount of zinc, 2 x 2 = 4 mol of acid reacts. This will synthesize 2 mol of hydrogen. Let’s calculate its volume. To do this, multiply the amount of substance by the volume of 1 mole of gas (which is 22.4 liters).
V H2 = 2 x 22.4 = 44.8 liters;
