Question

gold number is related to (i) Emulsification (ii) Coagulation

(iii) Protective Power (iv) Peptization .​

Answer 1

Answer:

I hope this will help you

Explanation:

The coagulation of gold sol results in an increase in particle size, indicated by a colour change from red to blue or purple. The higher the gold number, the lower the protective power of the colloid, because a greater amount of colloid is required to prevent coagulation.

Answer 2

Explanation:

1.

Emulsification is the process by which a system comprising of two immiscible liquids (usually oil and water), one of which is dispersed as small droplets within the other, is produced

2.

Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It potentially results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair

3.

protecting power is a country that represents another sovereign state in a country where it lacks its own diplomatic representation. It is common for protecting powers to be appointed when two countries break off diplomatic relations with each other.

4.

Peptization or deflocculation is the process of converting precipitate into colloid by shaking it with a suitable electrolyte called peptizing agent. ... When colloidal particles bear a same sign electric charge, they mutually repel each other and cannot aggregate together.
