Comment on the statement that “colloid is not a substance a state of substance.”
Answer:
The nature of the substance whether colloid or crystalloid depends upon the particle size. When the size of the solute particles lies between 1000-10000 pm, it behaves like a colloid and in case it is less than this value, it gives the characteristics of crystalloid. Thus, colloid is not a substance but it is state of a substance which depends upon the particle size.
