Current Question (ID: 18439)

Question:

$\text{Brownian movement is caused by:}$

Options:

1. $\text{Colloidal solution.}$
2. $\text{True solution.}$
3. $\text{Suspension having size } < 1000 \text{ m}\mu.$
4. $\text{All of the above.}$

Solution:

$\text{HINT: Random or zig-zag motion of the colloidal particles in a sol is called Brownian motion or Brownian movement.}$ $\text{Explanation:}$ $\text{It's a basic property of colloidal solution.}$ $\text{In true solution, very few examples are there, i.e. Pollen grains also move irregularly in water, i.e., lighter and smaller suspended particles. In the true solution of sugar, the sugar particles are also in motion in solution.}$ $\text{So, option 1 is the correct answer.}$ $\text{The graph between size and Brownian movement is as follows:}$ $\text{It is experimental data that shows that as the size of a colloidal particle increases the Brownian movement decreases.}$
