Regarding the bicarbonates (hydrogen carbonates) of s-block elements, which of the following stateme — s Block Elements Chemistry Question

💡 Solution & Explanation

All Group 2 bicarbonates and $LiHCO_3$ exist only in aqueous solution due to high cation polarizing power. Stability of Group 1 solid bicarbonates increases down the group as polarizing power drops. Statement D is false; heating $NaHCO_3$ yields $Na_2CO_3$, $H_2O$, and $CO_2$, not $NaOH$.
