Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
When soap is added to water micelle formation takes place through hydrophobic and hydrophilic ends of soap. Soaps are long chains of salts of fatty acids $R C O O^{-}$ where $R$ is hydrophobic part and $C O O^{-}$ and since it is negatively charged ,they do not coalesce and a stable emulsion is formed.
So both assertion and reason are correct and is correct explnation and correct answer is A.

Lithium sulphate does not form alums.

Reason

$L i^{+}$ is too small to form a stable lattice required for double-salt/alum formation.

Assertion – The non-fusible impurities present in iron ore are removed by $C a C O_{3}$ .

Reason: $C a C O_{3}$ which decomposes into $C a O$ and $C O_{2}$ . The $C a O$ formed reacts with $S i O_{2}$ to remove silica
