Vedclass · Answer

(D) Sodium stearate $(C_{17}H_{35}COONa)$ is the sodium salt of stearic acid and acts as a soap.When dissolved in water,it forms micelles due to the aggregation of its long hydrocarbon chains and polar carboxylate heads.These micelles have a size range of $1 \ nm$ to $1000 \ nm$,which is characteristic of a colloidal solution.Therefore,sodium stearate forms a colloidal solution in water.
