When a metal rod M is dipped into an aqueous colourless concetrated so – InterviewSolution

InterviewSolution

1.	When a metal rod M is dipped into an aqueous colourless concetrated solution of compound N, the solution turns light blue. Addition of aqueous NaCl to the blue solution gives a white precipitate O. Addition of aqueous `NH_3` dissolves O and gives an intense blue solution. Q. The compound N isA. `AgNO_3`B. `Zn(NO_3)_2`C. `Al(NO_3)_3`D. `Ph(NO_3)_2`
Answer» Correct Answer - A White ppt. of `O` Is of `AgCl` Since, `AgNO_3` is completely soluble silver compound, N is `AgNO_3`.
