Comment on the statement that `"` colloid is not a substance but state of a substance `"`

Text Solution

Verified by Experts

This statement is true because the ssame substance in one solvent may behave as a colloid while in the other as ctustalloid. For example, sodium chloride behaves as crystalloid in water but as colloid in benzene solvent. This means that the colloid is not a substance. It depends upon the particle size of the dispersed phase which varies from `10^(3)` to `10^(6)` pm. For more details, consult Section 14.
