Answer» Solution :(i) Medicine :- Drugs cure diseases by adsorption on BODY tissues. (II) Metallurgy:- Sulphide ores are concentrated by a process called froth floation in which lighter ORE particles are adsorbed by pine oil. (iii) MORDANT and Dyes:- Most of the dyes are adsorbed on the surface of the fabric. Mordants are the sustances used for fixing dyes onto the fabric. (iv) In the precipitation titrations, the end point is indicated by an external indicator which changes its colour after GETTING absorbed on precipitate. It is used to indicate the end point of filtration. |
