Reference no: EM13513642

A 0.2570g of pure sulfamic acid, HSO3 . NH2, is neutralized by a KOH solution. A 25.70 mL of KOH was added to the solution and 3.40 mL of HCl was used to back titrate the solution. In the ratio determination of 23.10 mL, HCl was used to completely neutralize 20.00 mL of KOH. Find the normality of the acid and base.
