C. pH of `CH_3 COOH` increase on dilution
D. pH of `NH_(3(aq)) ` decrease on dilution

Answer

A, B, C, D

Explanation

`pH downarrow ` because `kw uparrow " with " T " as " T uparrow , alpha uparrow `
` [H^(+) ] = sqrt( CK_a) , " hence as " C downarrow , [H^(+) ] downarrow rArr pH uparrow `
`..... POH uparrow i.e. ,pH uparrow `
