(B) $1$. Soap solutions form associated colloids (micelles) above the Critical Micelle Concentration $(CMC)$. This statement is true.$2$. Lyophilic colloids are reversible sols,meaning they can be easily reformed by mixing the dispersed phase with the dispersion medium after evaporation. The statement that they are irreversible is false.$3$. Blood is a colloidal system,and its purification (removal of urea and other waste products) is indeed carried out by the process of dialysis. This statement is true.$4$. Blood is a negative sol. Addition of excess electrolytes like $Ca^{2+}$ and $K^{+}$ causes coagulation due to the neutralization of charge. This statement is true.Therefore,the statement that is not true is $B$.
