A 2.89 g sample of limestone (CaCO3) was dissolved in 0.12M(HCI) solution according to the following equation:CaCO3 (s) + 2HCI (aq) → Ca²+ (aq) + 2Cl(aq) + CO2(g) + H₂O(1)Excess 0.1M (NH4)2C2O4(aq), was added to the resulting solutionto precipitate the calcium ions as calcium oxalate, CaC₂O4(s).The precipitate was filtered, dried, and weighed at 1.75 g.
