उत्तर
The colour of the colloidal particles of gold obtained by different methods differs because of different diameters of colloidal particles.
Explanation:
The colour of colloidal gold particles differs due to the variation in the size (diameter) of the particles, which affects how they scatter and absorb light, leading to different colours. Other factors like valency or impurities do not primarily cause this change in colour.
