MCQ (More than One Correct Answer)

-1

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

$$M{n^{2 + }}$$ shows the characteristic green color in the flame test

Only $$C{u^{2 + }}$$ shows the formation of precipitate by passing $${H_2}S$$ in acidic medium

Only $$M{n^{2 + }}$$ shows the formation of precipitate by passing $${H_2}S$$ in faintly basic medium

$$C{u^{2 + }}/Cu$$ has higher reduction potential than $$M{n^{2 + }}/Mn$$ (measured under similar conditions)
