Question

Calculate the volume in ml of 0.20m naoh needed to react completely with 100.ml of 0.040m acetic acid.

Answer 1

Hello!

You'll need 20 mL of 0,20 M NaOH to react completely with 100 mL of 0,040 M Acetic Acid.

The reaction between NaOH and Acetic Acid is the following:

NaOH + CH₃COOH → H₂O + CH₃COONa

To calculate the volume of 0,20 M NaOH needed to react completely with 100 mL of 0,040 M Acetic Acid, we'll need to use the following equation (Molar equivalence) and clear for Volume of NaOH:


`M_(NaOH)*V_(NaOH)=M_(CH_3COOH)*V_(CH_3COOH) \\ \\ V_(NaOH)= (M_(CH_3COOH)*V_(CH_3COOH) )/(M_(NaOH)) \\ \\ V_(NaOH)= (0,040M*100 mL )/(0.20)}=20 mL`

Have a nice day!
