Point out the false statement.a)Brownian movement and Tyndall effect a...
Explanation:

Colloidal Solution of a Liquid in Liquid:
The statement "The colloidal solution of a liquid in liquid is called gel" is false. A gel is actually a colloidal system in which the dispersed phase is a solid and the dispersion medium is a liquid. When a liquid is dispersed in another liquid to form a colloidal system, it is called an emulsion, not a gel. Emulsions can be further classified as oil-in-water (o/w) or water-in-oil (w/o) depending on the nature of the dispersed phase.

Other Statements:
- Brownian movement and Tyndall effect are indeed shown by colloidal systems. Brownian movement refers to the random motion of particles in a colloidal solution due to collisions with solvent molecules, while the Tyndall effect is the scattering of light by colloidal particles.
- The Gold number is a measure of the protective power of a lyophilic colloid, indicating the minimum amount required to prevent the coagulation of a lyophobic sol.
- The Hardy-Schulze rule is related to the coagulation of colloids based on the charge and valency of ions present in the dispersing medium.
Therefore, the false statement in the given options is the one referring to the colloidal solution of a liquid in liquid being called a gel.

Similar NEET Doubts

Read the passage given below and answer the following questions:Some colloids are stable by their nature, i.e., gels, alloys, and solid foams. Gelatin and jellies are two common examples of a gel. The solid and liquid phases in a gel are interspersed with both phases being continuous. In most systems, the major factor influencing the stability is the charge on the colloidal particles. If a particular ion is preferentially adsorbed on the surface of the particles, the particles in suspension will repel each other, thereby preventing the formation of aggregates that are larger than colloidal dimensions. The ion can be either positive or negative depending on the particular colloidal system, i.e., air bubbles accumulate negative ions, sulphur particles have a net negative charge in a sulphur sol, and the particles in a metal hydroxide sol are positively charged. Accumulation of charge on a surface is not an unusual phenomenon-dust is attracted to furniture surfaces by electrostatic forces. When salts are added to lyophobic colloidal systems the colloidal particles begin to form larger aggregates and a sediment forms as they settle. This phenomenon is called flocculation, and the suspension can be referred to as flocculated, or colloidally unstable. If the salt is removed, the suspension can usually be restored to its original state; this process is called deflocculation or peptization. The original and restored colloidal systems are called deflocculated, peptized, or stable sols. Why does a small amount of salt have such a dramatic effect on the stability of a lyophobic colloidal system? The answer lies in an understanding of the attractive and repulsive forces that exist between colloidal particles. Van der Waals forces are responsible for the attractions, while the repulsive forces are due to the surface charge on the particles. In a stable colloid, the repulsive forces are of greater magnitude than the attractive forces. The magnitude of the electrical repulsion is diminished by addition of ionized salt, which allows the dispersed particles to aggregate and flocculate. River deltas provide an example of this behaviour. A delta is formed at the mouth of a river because the colloidal clay particles are flocculated when the freshwater mixes with the salt water of the oceanQ. The particles in suspension will repel each other, thereby preventing the formation of aggregates that are larger than colloidal dimensions. This statement explains
