25 Questions

What is the characteristic of the particles in the suspension?

Weakly bonded

What happens to the particles in the suspension over time?

They settle rapidly

Do the particles in the suspension form a fence or aggregate?

Is it easy to resuspend the particles in the suspension?

Yes

What is the role of surfactants in the suspension?

To facilitate particle resuspension

Why is a very high positive electrode potential not preferred in the preparation of Dension?

It is not preferred because its value should be controlled within a certain limit.
