An aqueous solution of inorganic compound00 gives following reactions:(I)with an aqueous solution of bariun chloride aprecipitate insoluble in dil. HCl is obtained.(ii) Addition of access of Ky gives a brown ppt, which turnswhite on addition of excess of hypo.(iii) With an aqueous solution of K [Fe(CN).), a chocolatecoloured precipitate is obtainedIdentify (X) and give equations for the reaction (I),(ii) and(iii) |

Answer» Answer: (i) : Copper sulphate reacts with barium chloride to form white PRECIPITATE of barium sulphate. CuSO 4
+BaCL 2
⟶BaSO 4
(whiteppt)+CuCl 2
White precipitate of BaSO 4
is insoluble in dilute HCL. (II) : 2CuSO 4
+4KI⟶Cu 2
I 2
↓(browncolor)+I 2
+2K 2
SO 4
It TURNS white on addition of excess of hypo. (iii) : Copper sulphate reacts with potassium ferrocyanide to obtain chocolate coloured precipitate of cupric ferrocyanide. 2CuSO 4
+K 4
[Fe(CN) 6
]⟶Cu 2
[Fe(CN) 6
](chocolatecolouredprecipitate)+2K 2
SO 4 please answer my question |
