What volume of carbon dioxide is required for the complete reaction with a solution containing 0.4 mol of potassium silicate?
1. Let’s write down the reaction equation:
K2SiO3 + CO2 = K2CO3 + SiO2.
2. According to the reaction equation, we find the amount of carbon dioxide, and then its volume (Vm – molar volume, constant equal to 22.4 l / mol):
n (CO2) = n (K2SiO3) = 0.4 mol.
V (CO2) = n (CO2) * Vm = 0.4 mol * 22.4 l / mol = 8.96 l.
Answer: V (CO2) = 8.96 liters.
