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

Text Solution

Verified by Experts

The given statement is true . This is because the statement may exist as a colloid under certain conditions and as a crystalloid under certain other conditions . E.g., NaCl in water behaves as a crystalloid while in benzene , behaves as a colloid (called associated colloid ). It is the size of the particles while matters i.e., the state in which the substance exist . If the size of the particles lies in the range 1 nm to 100 nm it is in the colloid state.

  • Collidal solution is a heterogeneous solution which contains particle of intermediate size, i.e., (diameter between 1 and 1000 nm) colloidal is not a substance but it is a state of a substance which depends upon the molecular size. Colloidal solutions are intermediate between ture solution and suspensions. The size of the colloidal particles lies in the range

    A
    `10nm-1000nm`
    B
    `10mmu-1000mmu`
    C
    `1nm-1000nm`
    D
    `10^(-5)cm-10^(-7)cm`
