We're being asked to calculate the mass of Ca(OH)2 is required to react with the acetic acid in 25.0 mL of a solution having a density of 1.065 g/mL and containing 58.0% acetic acid by mass.
We're given the balanced reaction: 2 CH3CO2H + Ca(OH)2 ⟶ Ca(CH3CO2)2 + 2H2O
Step 1: Calculate the mass of CH3CO2H.
Recall that mass percent is given by:
Calculate the mass of the solution:
volume of solution (density) → mass solution
mass solution = 26.625 g
Calculate the mass of the CH3CO2H:
A mordant is a substance that combines with a dye to produce a stable fixed color in a dyed fabric. Calcium acetate is used as a mordant. It is prepared by the reaction of acetic acid with calcium hydroxide.
2 CH3CO2 H + Ca(OH)2 ⟶ Ca(CH3CO2)2 + 2H2O
What mass of Ca(OH)2 is required to react with the acetic acid in 25.0 mL of a solution having a density of 1.065 g/mL and containing 58.0% acetic acid by mass?
