When negatively charged colloid like sol is added to positively charged sol in stoichiometric amounts
Options:(select one or more)
Answer:
A, B
Solution:
When oppositely charged colloids are mixed in suitable (stoichiometric) amounts, their charges neutralize each other.
As a result, the colloidal particles lose stability and get coagulated or precipitated.
This phenomenon is called mutual coagulation.
Hence both sols precipitate simultaneously.
After neutralization, no excess charge remains on particles, so they do not become positively or negatively charged colloids
