37295 Nitrate is confirmed by ring test. The brown colour of the ring is due to the formation of

1 Ferrous nitrite
2 \(FeS{O_4}NO\)
3 \(FeS{O_4}N{O_2}\)
4 Ferrous nitrate
PRACTICAL CHEMISTRY

37296 Which of the following precipitate does not dissolve even in large excess of \(N{H_4}OH\)

1 \(AgCl\)
2 \(AgBr\)
3 \(AgI\)
4 None of these
PRACTICAL CHEMISTRY

37297 Aqueous solution of a salt when treated with \(AgN{O_3}\) solution gives a white precipitate, which dissolves in \(N{H_4}OH\). Radical present in the salt is

1 \(C{l^ - }\)
2 \(B{r^ - }\)
3 \({I^ - }\)
4 \(NO_3^ - \)
PRACTICAL CHEMISTRY

37298 When \(C{O_2}\) is passed into lime water it turns milky. When excess of \(C{O_2}\) is passed, milkyness disappears because

1 Reaction is reversed
2 Water soluble \(Ca{(HC{O_3})_2}\) is formed
3 Vaporisable calcium derivative is formed
4 None of these
