(i) A salt solution on treatment with neutral FeCl_3 gives a brown coloured solutioheating the solution a brown coloured ppt is obtained. When the solution is inwith Kl solution, a straw yellow.coloured ppt, is obtained. Identify the salt (ii)W on passing HS though a salt solution a brown ppt, is obtained. On adding wate an acidic solution of the salt, turbidity was observed. Identify the cation in the salt |

Answer» Solution :(i) The given SALT is COPPER acetate `3CH_3COO^(-)+FeCl_3to(Ch_3COO)_3Fe+#Cl^(-)` `(Ch_3COO)_3Fe+2H_2Ooverset(Delta)to (CH_3COO)Fe(OH)_(2)+2CH_3COOH` `Hence the acid RADICAL present in the salt is acetate radical. `2CU^(2+)+4kltoCu_(2)l_2+4k^(+)+l_2` (ii) The formation of a brown precipiatewith `H_2S` indicate `Bi^(3+)` or `Sn^2+` `2Bi^(3+)+3H_2StoBiS_3+6H^+` `BiCl_3+H_2Oto BiOCl+2HCl` |
