Vedclass · Answer

(D) Due to the very small ionic radius of $Li^+$,it shows anomalous behavior compared to other members of the group.$1$. $Li_2SO_4$ has low solubility in water compared to other alkali metal sulphates.$2$. All alkali metal sulphates except $Li_2SO_4$ form alums with trivalent metal sulphates (e.g.,$M_2SO_4 \cdot M_2'(SO_4)_3 \cdot 24H_2O$).$3$. Alkali metal sulphates are generally stable to heat,but $Li_2SO_4$ decomposes at high temperatures,whereas others do not.Therefore,all the given statements are correct.

Which of the following statements about the sulphates of alkali metals is correct?
