Question

Which of the following techniques is used for reducing the total dissolved solids (TDS) in the

water?

(a) Osmosis

(b) Ion exchange

(c) Distillation

(d) Both b and c​

Answer 1

The correct answer is option (d) Both b and c.

Explanation:

• Osmosis and Distillation techniques is used for reducing the total dissolved solids (TDS) in the water.
• Total dissolved solids is a measure of the dissolved combined content of all organic and inorganic substances present in a liquid.
• Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation.
• Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
