Assertion :Lyophilic colloids such as starch, gelatin etc., act as protective colloids. Reason: Protective power of lyophilic colloids is expressed in terms of gold number.
Assertion :Lyophilic colloids such as starch, gelatin etc., act as protective colloids. Reason: Protective power of lyophilic colloids is expressed in terms of gold number.
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The assertion is correct because lyophilic colloids are used to prevent the coagulation of lyophobic colloid by addition of electrolyte is called Protection of colloidal sol. Thus lyophilic colloids are called protective colloid. The reason is also correct because the protective power of lyophilic colloids are expressed in term of gold number as protective power is inversely proportional to the gold number. The reason is correct but not explaining assertion. Thus, both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Thus Option B is correct.
