An unknown inorganic compound `(X)` gave the following reactions:
(i) The compound `(X)` on heating gave a residue, oxygen and oxide of nitrogen.
An aqueous solution of compound `(X)` on addition to tap water gave a turbidity which did not dissolve in `H_(3)O^+`
(iii) The turbidity dissolved in `NH_(4)OH` .
Identify the compound `(X)` and gives equation for the reaction (i),(ii) & (iii)`

Text Solution

Verified by Experts

The correct Answer is:
`X=AgNO_(3)`.
`2AgNO_(3)(X)overset(Delta)to2Ag+2NO_(2)+O_(2)`.
`AgNO_(3)(aq.)+Cl^(-)toAgCldarr("white")+NO_(3)^(-)`
`AgCl+2NH_(3)to[Ag(NH_(3))_(2)]^(+)("soluble complex")`.
