Distinguishing between Nitrate Salts of Mn2 and Cu2

Flame Test:

- Mn2 shows a characteristic pale pink colour in the flame test, not green.
- Cu2 shows a characteristic green colour in the flame test.

Formation of Precipitate by Passing H2S:

- Only Cu2 shows the formation of a black precipitate of CuS by passing H2S in acidic medium.
- Mn2 does not form a precipitate with H2S in acidic medium.

Reduction Potential:

- Cu2/Cu has a higher reduction potential than Mn2/Mn, measured under similar conditions.
- This means that Cu2/Cu is more easily reduced than Mn2/Mn, and will form a solid (precipitate) more readily when H2S is passed through it in an acidic medium.

Conclusion:

- The correct options to distinguish nitrate salts of Mn2 and Cu2 taken separately are B and D.
- Only Cu2 shows the formation of a precipitate by passing H2S in acidic medium, and Cu2/Cu has a higher reduction potential than Mn2/Mn.
