Answer» Solution :Basic BUFFER ` to POH =pKb+ log ""(S)/(B) ` ` rArr PH =(pK_a) +log ""( B)/(S) ` ACID buffer ` to pH =pK_a +log ""(S)/(A) ` `WA + SB rArr ` anion hydrolysis `rArr pH =7+ ((pKa+ logc )/( 2))` ` WB+SA rArr ` cation hydrolysis ` rArr pH =7- ((pK_b+log c)/( 2))` `WB +SA rArr ` cation hydrolysis ` rArr pH= 7- ((pK_b+log c)/(2))`
