Chemistry - Salt Analysis Question with Solution | TestHub

The correct option(s) to distinguish nitrate salts of$\mathrm{M}{\mathrm{n}}^{2+}$and$\mathrm{C}{\mathrm{u}}^{2+}$taken separately is (are)

(1)$\mathrm{M}{\mathrm{n}}^{2+}$shows the characteristic green colour in the flame test

(2) only$\mathrm{C}{\mathrm{u}}^{2+}$shows the formation of precipitate by passing${\mathrm{H}}_2\mathrm{S}$in acidic medium

(3) only$\mathrm{M}{\mathrm{n}}^{2+}$shows the formation of precipitate by passing${\mathrm{H}}_2\mathrm{S}$in faintly basic medium

(4)${\text{Cu}}^{2+}|\text{Cu}$has higher reduction potential than${\text{Mn}}^{2+}|\text{Mn}$(measured under similar conditions)
