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: A salt solution is an example of a homogenous mixture. A homogenous mixture is a mixture whose composition remains the same and does not change at all. In a homogenous solution, the size of the particle is too small as its diameter is less than $1\,nm$. In short, they are not visible to the naked eye.

Complete step by step answer:
Salt solution is a true solution. Particles present in a true Solution diffuse quickly through filter paper and parchment paper. Salt solution is a transparent solution.
Any solution whether it is homogeneous or heterogeneous. It is always composed of two or more substances. The substance which is dissolved and is present in the minor proportion is called the solute while the substance in which the solute is dissolved and is present in the major proportion is called the solvent.
Salt solution is an example of an aqueous solution. It means that salt is dissolved in water and the component which is dissolved is called the solute. Therefore, salt will be the solute and water will be the solvent.
When $NaCl$ is dissolved in water, it dissociates into $N{a^ + }$ and $C{l^ - }$ ions. The presence of ions should make the solution ionic but the solution remains neutral because the amount of $N{a^ + }$ and $C{l^ - }$ ions in the solution remains the same. Hence, the solution remains neutral.
Now, we can say that in a salt solution $NaCl$ is the solute and water is the solvent.

Therefore, Option (B) is correct.

Note:
 In a true solution, the solute and solvent particles cannot be separated through a simple distillation process. Particles of a true solution do not scatter when a beam of light passes through them and hence does not show the Tyndall effect.
