Vedclass · Answer

(C) Calcium oxide $(CaO)$,calcium carbonate $(CaCO_3)$,and calcium hydroxide $(Ca(OH)_2)$ are basic in nature and react with acetic acid $(CH_3COOH)$ to form soluble calcium acetate $(Ca(CH_3COO)_2)$.$CaO + 2CH_3COOH \rightarrow Ca(CH_3COO)_2 + H_2O$$CaCO_3 + 2CH_3COOH \rightarrow Ca(CH_3COO)_2 + H_2O + CO_2$$Ca(OH)_2 + 2CH_3COOH \rightarrow Ca(CH_3COO)_2 + 2H_2O$Calcium oxalate $(CaC_2O_4)$ is a salt of a strong acid (oxalic acid) and is insoluble in weak acids like acetic acid.
