As a result of hydrolysis of calcium carbide, 8.96 liters of gas were released. What volume of a 10% solution of hydrogen chloride with a density of 1.05 g / ml is required to neutralize the remaining solution?
CaC2 + H2O = C2H2 ↑ + Ca (OH) 2
2HCl + Ca (OH) 2 = 2H2O + CaCl2
n (C2H2) = 8.6 / 22.4 = 0.38 mol
m (HCl) = 0.76 x 36.5 = 28 g
0.76 = (V x 0.1 x 1.05) / 36.5
⇒ V = 264.2 ml
Answer: the volume of the hydrogen chloride solution required to neutralize the remaining solution is 264.2 ml.
