Answer :
Titration is a neutralization reaction with an acid and a base. The concentration of calcium hydroxide Ca(OH)₂ in the reaction is 0.04267 M
How to calculate the concentration reaction?
Given:
Concentration HCl : M₁ = 0.028 M
Volume HCl = V₁ = 38.1 mL
Volume Ca(OH)₂: V₂ = 25.0 mL
Asked:
Concentration Ca(OH)₂: M₂ = ?
Answer:
Formula to answer this question → M₁V₁ = M₂V₂
0.028 x 38.1 = M₂ (25.0)
M₂ = 1.0668/25.0
M₂ = 0.04267 M
So, the concentration of calcium hydroxide in the reaction is 0.04267 M
