D is a solution containing 0.05mol/dm3 of H2SO4
E is a solution containing 7.50g/dm3 of impure KOH
Solution D was titrated against 25.0cm3 portions of E by a student using methyl orange as indicator. Calculate the percentage impurity in an impure solution of E
1 answer
And how much H2SO4 was needed to titrate the impure kOH? You gotta know that.
