Question

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. 2CH₃CO₂H+Ca(OH)₂⟶Ca(CH₃CO₂)2+2H₂O.

What is the balanced chemical equation for the reaction?
a) 2CH₃CO₂H+Ca(OH)₂⟶Ca(CH₃CO₂)₂+2H₂O
b) 3CH₃CO₂H+Ca(OH_)2⟶Ca(CH₃CO₂)₂+2H₂O
c) CH₃CO₂H+Ca(OH)₂⟶Ca(CH₃CO₂)₂+H2O
d) 2CH₃CO₂H+2Ca(OH)₂⟶Ca(CH₃CO₂)₂+2H₂O

Answer 1

The balanced chemical equation for the reaction of acetic acid with calcium hydroxide to produce calcium acetate and water is 2CH3CO2H + Ca(OH)2 → Ca(CH3CO2)2 + 2H2O, which corresponds to option a).

Step-by-step explanation:

The balanced chemical equation for the reaction between acetic acid (CH3CO2H) and calcium hydroxide [Ca(OH)2] to produce calcium acetate [Ca(CH3CO2)2] and water (H2O) is given by option a):

2CH3CO2H + Ca(OH)2 → Ca(CH3CO2)2 + 2H2O

This reaction is an example of a neutralization reaction where an acid reacts with a base to produce a salt and water. It is important in various applications including the use of calcium acetate as a mordant in dyeing fabrics.
