Question

What volume in mL of a 0.121 M sodium hydroxide solution is required to reach the equivalence point in the complete titration of a 10.0 mL sample of a 0.102 M sulfuric acid? (Hint: write the equation out)

Answer 1

16.9 mL

Step-by-step explanation:

This is NOT a dilution problem!! Always remember that dilution problems only deal with a single compound, not multiple. If multiple chemicals or compounds are mentioned, do not try to use M1V1=M2V2, it will not work!

Answer 2

8.42 mL

Step-by-step explanation:

For the equivalence point for the reaction of an acid and base , is given by the following formula -

M₁V₁ = M₂V₂

where ,

M₁ = acid's concentration ,

V₁ = acid's volume ,

M₂ = base's concentration ,

V₂ = base's volume .

from , the question ,

M₁ = 0.102 M ( acid )

V₁ = 10.0 mL ( acid )

M₂ = 0.121 M ( base )

V₂ = ?

To calculate the volume of the base , the above formula is used and the respective values are substituted , as follow -

M₁V₁ = M₂V₂

0.102 M * 10.0 mL = 0.121 M * V₂

V₂ = 1.02 / 0.121 = 8.42 mL
