Select the correct statements.
ABaSO4 dissolves readily in dilute hydrochloric acid
BThe solubility of alkali metal fluorides in water increases from LiF to CsF
CLiF is more soluble in water than CsF
DThe solubility of group 2 sulphates in water decreases from BeSO4 to BaSO4
Answer: B, D
LiF is least soluble because of its very high lattice enthalpy, and the fluorides become more soluble down the group. Group 2 sulphates decrease in solubility down the group, and BaSO4 is insoluble even in dilute acids.
