Problem
A 1.7225 g of metal (bivalent) salt Ax(CO3)y(OH)z was dissolved to prepare 100 mL solution. 50 mL of this solution required 10 mL 1.0 *N* H2SO4 solution to reach the equivalence point using phenolphthalein as indicator. Another 50 mL solution using methyl orange
as indicator required 15 mL of same acid. Deduce the formula of salt.
