Question

Observe the figures given below, the proper sequence of the content in the glass beaker is

• A. Suspension, colloidal, and true solution
• B. True solution, colloidal, and Suspension.
• C. True solution, Suspension, and colloidal
• D. Colloidal, Suspension, and True solution,

Answer 1

The correct option is B

True solution, colloidal, and Suspension.

The explanation for the correct option-

Suspensions: A heterogeneous mixture of insoluble particles of solute, spread throughout a solvent, is called a suspension. The particle size (diameter) in a suspension is more than 10^-5 cm. The particles have a tendency to settle down at the bottom of the vessel and can be filtered out because their size is bigger
than the size of the pores of the filter paper. More scattering of light takes place in suspensions, because of the bigger size of particles.

Example: Sand and water

Colloidal Solutions: A heterogeneous solution in which the particle size is between 10^-7 cm to 10^-5 cm, such that the solute particles neither dissolve nor settle down in a solvent is called a colloidal solution. when a strong beam of light is passed through a colloidal solution and viewed at right angles with the help of a
microscope, the path of light shows up a bright cone of bluish light.

Example: White of an egg. Starch Paste

True Solution: A homogeneous mixture of two or more substances is called a solution. Usually, we think of a solution as a liquid that contains either a solid or a liquid or a gas dissolved in it. However, this is not true. We can also have a solid solution and gaseous solution as in the case of alloys and air respectively.

Example: sugar in water.

A true solution is always clear and transparent, i.e., light can easily pass through it without scattering.

Hence, Option(B) is correct option.
