Question

Titration is a type of experiment that can be performed to investigate a neutralization reaction. The equivalence point is when all of the acid and base is fully neutralized. A sample of 0.756 M aqueous potassium hydroxide was titrated against a standard solution of hydrochloric acid. What was the volume of the potassium hydroxide solution if 67.7 mL of 1.50 M hydrochloric acid was needed to reach the equivalence point

Answer 1

Answer:

V₂ = 134.32 mL

Explanation:

In case of titration , the following formula can be used -

M₁V₁ = M₂V₂

where ,

M₁ = concentration of acid ,

V₁ = volume of acid ,

M₂ = concentration of base,

V₂ = volume of base .

from , the question ,

M₁ = 1.50 M

V₁ = 67.7 mL

M₂ = 0.756 M

V₂ = ?

Using the above formula , the volume of base , potassium hydroxide , can be calculated as ,

M₁V₁ = M₂V₂  

1.50 M * 67.7 mL = 0.756 M * V₂

V₂ = 134.32 mL
