Solution:
Coloured Solutions
A solution is a homogeneous mixture of two or more substances. The solution is said to be coloured when it absorbs a particular wavelength of light and reflects the remaining wavelengths. The colour of the solution depends on the nature of the solute and solvent molecules present in it. Let's see which of the following solutions is coloured.
Given that the options are ZnSO4, FeSO4, Al2(SO4)3, and Na2SO4.
- ZnSO4: Zinc sulphate is a white crystalline solid that dissolves in water to form a colourless solution. Hence, ZnSO4 is not a coloured solution.
- FeSO4: Ferrous sulphate is a greenish-blue crystalline solid that dissolves in water to form a pale green-coloured solution. Hence, FeSO4 is a coloured solution.
- Al2(SO4)3: Aluminium sulphate is a white crystalline solid that dissolves in water to form a colourless solution. Hence, Al2(SO4)3 is not a coloured solution.
- Na2SO4: Sodium sulphate is a white crystalline solid that dissolves in water to form a colourless solution. Hence, Na2SO4 is not a coloured solution.
Hence, the correct answer is option B, FeSO4.
