How many ml of 0. 10 m naoh should the student add to 20 ml of 0. 10 m hf or if she wished to prepare a buffer with a ph of 3. 55, the same as in problem 4

Sagot :

The required volume of 0.10M NaOH solution that student will add is 20 mL.

How do we calculate the volume?

Volume of any solution which is required to prepare buffer will be calculated by using the below equation as:

M₁V₁ = M₂V₂, where

  • M₁ & V₁ are the molarity and volume of NaOH solution.
  • M₂ & V₂ are the molarity and volume of HF solution.

On putting values, we get

V₁ = (0.1)(20) / (0.1) = 20mL

Hence required volume of NaOH solution is 20mL.
