Question

To know the difference between true solutions, colloids and suspension.

Prepare all the three types of solutions (Name them A, B and C) and after studying the

mechanisms involved, write the answers to the following questions in your Chemistry

notebooks. Describe the activity (with its aim, materials required, procedure, and

conclusion)

Q1. Were you able to see the particles in the mixture of any (A, B, and C)?

Q2. Have you observed the path of beam of light visible when passed through

beaker containing mixture?

Q3. Have you observed any settling of particles of the mixture after sometime or is

it stable?

Q4. Have you observed any residue left on the filter paper after filtration?​

Answer 1

Answer:

True solution - Salt solution, copper sulphate solution, sugar and water solution, vinegar, air, brass.

Colloidal solution - Milk, Blood, Soap solution, starch solution, ink

Suspension - Milk of magnesia, chalk powder and water solution, flour in water, muddy water.

A true solution has extremely small particles which cannot reflect light, hence a true solution cannot exhibit ‘Tyndall effect’

Answer 2

Answer:

The true solution is the homogenous mixture, while Colloidal solution and Suspension are the heterogeneous mixtures of two or more substances. Another difference between these three types of solution is that the True solution is transparent, while the Colloidal solution is translucent and Suspension is opaque.
