Question

Assertion: Chalk powder
dissolved in water shows the Tyndall effect.

Reason: The chalk powder
particles suspended in water disperse light.​

Answer 1

Answer:

The chalk powder we take and we dusolved in water chalk powder is nothing but the small particles are remaining

Explanation:

suppose we take a something like paper than paper we would disolved in water than paper is rubber is taking

Answer 2

• Chalk doesn't totally dissolve in water when you try to dissolve it. The chalk powder settles to a point where it can clearly be seen with the naked eye.
• Consequently, a suspension is an example of chalk powder dissolved in water.

Tyndall effect.

• When light beams are directed towards a colloid of particles, the Tyndall effect causes them to be scattered.
• All colloidal fluids and certain extremely fine suspensions exhibit this effect. Consequently, it can be used to confirm whether a certain solution is a colloid.
• Both the frequency of the incident light and the density of the colloidal particles affect how much light is dispersed.

• Suspension refers to the heterogeneous combination in which the solute does not dissolve into the solution.
• Particles in suspension are greater than 1000A in size.

Explanation

• In genuine solutions, the solute entirely dissolves in the solvent. In a solvent in suspension, the solute does not dissolve. The suspended solute sinks to the bottom.
• Colloids still contain the solute, which is dispersed in a solvent. True solutions or colloid solute particles are invisible to the naked eye.
• Colloidal particles can settle down when subjected to strong centrifugal forces.
