Question

Salt dissolves in water to form salt solution. Name of the solvent is:
(A) Salt
(B) Water
(C) Salt-water
(D) Salt and water

Answer 1

Hint: We need to know the concept of solute and solvent. We already know that a solution is formed when solute and solvent are mixed together. The solvent is mostly the aqueous part which is present in a higher amount than the solute.

Complete step by step answer
We already know that; solvent is the substance in which a solute dissolves to produce a homogeneous mixture and solute is the substance that dissolves in a solvent to produce a homogeneous mixture.
Similarly, we can say that, Salt is dissolved in water to form salt water, so salt is present as a solute and water as a solvent.
So, we need to select the correct answer.
The correct answer is B.

Note
The solute is the substance which is dissolved by the solvent. For example, in a solution of salt and water, water is the solvent and salt is the solute as seen in the above question. Solutions are formed because the molecules of the solute are attracted to the molecules of the solvent.
When two liquids are mixed to form a solution, the solute is the species present in the smaller ratio. For example, in a sulfuric acid solution, sulfuric acid is the solute while water is the solvent. Similarly, sweet water has water as solvent and sugar as solute.
The terms solute and solvent can also be applied to alloys and solid solutions. Carbon may be considered a solute in steel.
Some examples of solvents are water, milk, Toluene, Acetone, ethanol, Glycerol, Petroleum, and Ether. Similarly, some other examples of solute are salt, Lemon, oxygen, carbon dioxide, Nitrogen and ethyl alcohol.
