The correct order of solubility is

1.	The correct order of solubility is
Answer» `CaCO_(3)ltKHCO_(3)ltNaHCO_(3)` `KHCO_(3)ltCaCO_(3)ltNaHCO_(3)` `NaHCO_(3)ltCaCO_(3)ltKHCO_(3)` `CaCO_(3)ltNaHCO_(3)ltKHCO_(3)` Solution :Biacarbonates are more soluble than carbonates and bicarbonates of IIA group ELEMENTS are more soluble than IA group. So the order of SOLUBLITY `CaCO_(3) lt NaHCO_(3) lt KHCO_(3)`
