Define a solution of h2so4 was standardized against a sample

Reference no: EM13507162

A solution of H2SO4 was standardized against a sample of CaCO3 (FW = 100) weighing 0.7242g. The same required 29.90 mL of the acid and the excess acid was back titrated with 10.20mL of NaOH solution. If 1.00mL of the acid will react with 1.02 mL of NaOH, WHAT IS THE M OF THE ACID AND OF NaOH?

CaCO3 + H2SO4 ---> CaSO4 + H2CO3 ( decomposes to CO2 and H2O)
