1.	The solubility of carbonates _____________ down the group.(a) is irregular(b) remains the same(c) decreases(d) increasesThis question was posed to me in class test.My question is based upon s-Block Elements topic in chapter s-Block Elements of Chemistry – Class 11
Answer» Correct choice is (d) increases To explain: The solubility of carbonates and BICARBONATES of alkali metals increases on moving down the group, this is due to the INCREASE in LATTICE enthalpies. The order is as follows in an increasing way of LITHIUM bicarbonate, sodium bicarbonate, POTASSIUM bicarbonate, rubidium bicarbonate, and cesium bicarbonate.
