Coagulation of Colloids

What is meant by coagulation of a colloidal solution? Name any method by which coagulation of lyophobic sols can be carried out.

What is meant by coagulation of a colloidal solution ? Describe briefly any three methods by which coagulation of a lyophobic sol can be carried out.

Coagulation of lymph is :

Protein required for coagulation of blood is

The cation (mineral) necessary for coagulation of blood is

Colloidal sulphur particles are negatively charged with S_(2) O_(3)^(2-) and other ions on the surface of sulphur. Hence, the most effective electrolyte in coagulating colloidal sulphur is:

The coagulation of blood occurs due to

The capacity of an ion to coagulate a colloidal solution depends on

Most effective coagulant for a colloidal solution of arsenic sulphide in water is

The particles of a particular colloidal solution of arsenic trisulphide (As_(2)S_(3)) are negatively charged. Which 0.0005 M solution would be most effective in coagulating this colloidal solution. KCl, MgCl_(2), AlCl_(3) or Na_(3)PO_(4) ? Explain.
