**Step-by-Step Text Solution:** 1. **Introduction to Brownian Movement:** Brownian movement refers to the random motion of small particles suspended in a fluid (liquid or gas). This phenomenon is named after the botanist Robert Brown, who first observed it in pollen grains suspended in water. 2. **Characteristics of Brownian Movement:** - The particles involved in Brownian movement are typically colloidal particles, which range in size from 1 to 1000 nanometers. - These particles are so small that they are influenced by the collisions with the molecules of the surrounding fluid. ...

Which type of property is the Brownian movement of colloidal sol.?

Which type of property is the Brownian movement of colloidal sol?

Assertion: The Brownian movement is due to the bombardment on colloidal particle by the molecules of dispersion midium which are in the constant motion like molecules in a gas. Reason: Brownian movement provides a visible proof of the random kinetic motion of molecules in a liquid.
