Answer:
A.®(4) B.®(3) C.®(1) D.®(2)
A. Purification of colloid can be done
by dialysis in which ions/particles are removed from solution through
semipermeable membrane.
B. Peptisation is a process in
which when small quantity of electrolyte (peptising agent) is added to precipitate.
It leads to formation of colloidal solution.
C. The process of removing of
oily or greasy dirt from the cloth is done by emulsification.
Dialysis
D. Process of setting of colloidal
particle is called coagulation. Electrophoresis is a process in which on
applying electric potential to the electrodes dipped in sol, the oppositely
charged particles of colloidal solution move towards oppositely charged
electrodes, get discharged and precipitated.
