Answer 1

Separating solids from liquids – filtration, chromatography.

12. As the dropper might contain some chemicals which might act as an impurity or it can also interact with the other chemicals we need to wash the dropper properly and dry it then we should use it again after use we should have to clean it after use. without washing it might create discrepancy in the result.
