Show Answer
Answer:
Correct Answer: D
Solution:
[d] Due to very small radius, Li shows different behaviour as compared to the other members of the group.
All sulphate salts of alkali metals except lithium sulphate form alum. All sulphate salts of alkali metals except lithium sulphate do not decompose at high temperatures.
$ Li_2SO_4 $ is least soluble in water.
Hence, all the given statements are correct.
