A blue colouration is not obtained when:a)Ammonium hydroxide dissolves...
Explanation:
When copper sulphate solution reacts with K4[Fe(CN)6], a blue colouration is not obtained. This is because of the following reasons:
1. Reaction between copper sulphate and K4[Fe(CN)6]:
CuSO4 + K4[Fe(CN)6] → Cu2[Fe(CN)6] + 4K2SO4
2. Formation of brown precipitate:
Cu2[Fe(CN)6] is a brown precipitate that is formed during the reaction. This precipitate masks the blue colouration that could have been observed if the reaction had not occurred.
3. The colour of Cu2[Fe(CN)6]:
Cu2[Fe(CN)6] is brown in colour due to the presence of iron in the compound. This brown colour masks the blue colour that is usually observed in the reaction between copper sulphate and other compounds like ammonium hydroxide and sodium ferrocyanide.
Conclusion:
Hence, a blue colouration is not obtained when copper sulphate solution reacts with K4[Fe(CN)6] due to the presence of Cu2[Fe(CN)6], which is a brown precipitate that masks the blue colour that could have been observed.
