1.	Assertion (A): The pH of a buffer solution containing equal moles of acetic acid and sodium acetate is 4.8 (pK_(a) of acetic acid is 4.8). Reasons (R): The ionic product of water at 25^(circ)C is 10^(-14) mol^(2)L^(-2).The correct answer is
Answer» <P>Both (A ) and (R ) are true and (R )is the correct explanation of (A ) Both (A) and (R ) are true and (R )is not the correct explanation of (A) (A ) is true but (R ) is FALSE (A ) is false but (R ) is true Solution :`P^(H)= PK a +log "" (S)/(A)=PKA (because S = A ) `
