Which of the following ions or compounds in a solution tend to produce an acidic ,a base or a neutral solution ?
(a)`C_(2)H_(5)O^(-),(b)Cu^(2-) (c ) SO_(3)^(2-) (d) F^(-) (e) NH_(4)^(+)`
`CH_(3)COOHNa (g) KNO_(3) (h) NaOCl (i) Na_(2)CO_(3),(j) ZnCl_(2)`

Explanation

(a) `C_(2)H_(5)O^(-)+H_(2)OrArr C_(2)H_(5)OH+OH^(-)("Basic solution")`
`(b) Cu^(+2)+2H_(2)OhArr Cu(OH)_(2)downarrow +2H^(+)("Acidic solution")`
`(c) SO_(3)^(2-)+H_(2)OhArr HSO_(3)^(-)+OH^(-)("Basic solution")`
`(d) F^(-)+H_(2)OhArr HF+OH^(-)("Basic solution")`
(e)`NH_(4)^(-)+H_(2)OhArr NH_(4)OH+H^(+)("Acidic solution")`
`(f)CH_(3)COONa+H_(2)OhArr CH_(3)COOH+Na^(+)+OH^(-).("Basic Solution")`
`(g) KNO_(3)+H_(2)OhArr K^(+)+NO_(3)^(-)+H_(2)O.("Neutral solution")`
`(h)NaOCl+H_(2)OhArr HOCl+Na^(+)+OH^(-).("Basic solution")`
`(i) Na_(2)CO_(3)+H_(2)OhArr HCO_(3)^(-)+2Na^(+)+OH^(-).("Basic solution")`
(j) `ZnCl_(2)+2H_(2)OhArr Zn(OH)_(2)downarrow+2Cl^(-)+2H^(+).("Acidic solution")`
