Current Question (ID: 18449)

Question:

$\text{Which of the following statement about multi-molecular colloid is incorrect?}$

Options:

1. $\text{They have a diameter of less than 1 nm.}$
2. $\text{When these particles are dissolved in a liquid, they form sol.}$
3. $\text{The molecules in the aggregate are held together by van der Waal's forces of attraction.}$
4. $\text{None of the above.}$

Solution:

$\text{A colloid is a mixture in which one substance of microscopically dispersed insoluble particles are suspended throughout another substance.}$ $\text{Multimolecular colloids are particles formed by the aggregation of smaller molecules when they are dissolved in a solvent.}$ $\text{Formed from particles having diameters less than 1 nm.}$ $\text{The aggregates are held together via weak Van der Waal forces.}$
