Match the nature of aqueous solutions of the substances listed in Column I with the character listed in Column II. {:(,"Column I",,"Column II"),((A),KCN_((aq)),(p),"Strongly basic"),((B),TiOH_((aq)),(q),"Neutral"),((C),BeCl_(2(aq)),(r),"Weakly basic"),((D),NaNO_(3(aq)),(s),"Weakly acidic"):}

Answer»


Solution :`(A)CN^(-)+H_(2)OrarrHCN+OH^(-)`
(Anionic HYDROLYSIS), `pHgt7`), weakly basic
`(B) TiOH"(STRONG base)"rarrTi^(+)+OH^(-)(pHgtgt7),` strongly basic
`(C)Be^(2+)+2H_(2)OrarrBe(OH)_(2)+2H^(+)("cationic hydrolysis "pHgt7 ), "weakly ACIDIC"`
`(D)NaNO_(3)" "("SALT of strong base NaOH and strong acid "HNO_(3))`
`rarr` No hydrolysis of the cation or the anion, pH=7 , neutral
