Answers
Answer:
a. Adding special chemicals or some natural coagulants can accelerate sedimentation. Three common chemicals used are aluminium sulphate, polyaluminium chloride (also known as PAC or liquid alum) and ferric sulphate(The techniques of dissolving, filtration and evaporation are used. The mixture of the two solids is added to water. The soluble solid is allowed to dissolve and the insoluble solid is filtered out. The soluble solid can then be obtained by evaporating the water..c.B). Centrifugation
Butter can be separated from curd by the process of Centrifugation. The principle behind this process is that the denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly.
