How much carbon dioxide is required to interact with 60 g of a 20% calcium hydroxide solution

How much carbon dioxide is required to interact with 60 g of a 20% calcium hydroxide solution, if the reaction results in a medium salt.

1. The reaction of calcium hydroxide with carbon dioxide occurs according to the equation:

Ca (OH) 2 + CO2 = CaCO3 + H2O;

2.Calculate the mass of calcium hydroxide:

m (Ca (OH) 2) = w (Ca (OH) 2) * m (Ca (OH) 2 solution) = 0.2 * 60 = 12 g;

3.Calculate the chemical amount of hydroxide:

n (Ca (OH) 2) = m (Ca (OH) 2): M (Ca (OH) 2);

M (Ca (OH) 2) = 40 + 2 * 17 = 74 g / mol;

n (Ca (OH) 2) = 12: 74 = 0.1622 mol;

4.determine the amount of carbon dioxide:

n (CO2) = n (Ca (OH) 2) = 0.1622 mol;

5. find the volume of carbon dioxide:

V (CO2) = n (CO2) * Vm = 0.1622 * 22.4 = 3.63 l.

Answer: 3.63 liters.
