Question

what volume of 0.125M sodium hyfroxide solution is needed to titrate 25.0 cm3 of 0.085M solution sulphuric acid​

Answer 1

Answer:

we use N1V1 = N2V2

n-factor ×M1V1 = n-factor × M2V2

1×0.125×V = 2×0.085×25

V= 2×25×0.085/0.125= 34ml

Explanation:

This is a case of acid-base neutralisation.
