Question

Which describes a species in which the solvent is water?
A) Solute
B) Solvent
C) Solubility
D) Aqueous Solution
E) Solvation

Answer 1

A solution is formed by dissolving solute with a solvent. Water is considered as a universal solvent and can dissolve maximum amounts of solute in it. The word aqueous means water. The solution which has water as the solvent is known as aqueous solution.

Complete answer:
A solution is homogeneous in nature which contains a mixture of solute and solvent. The solution is said to be homogenous which means that the ions present are mixed uniformly such that the solute and solvent cannot be differentiated. Whereas in heterogeneous solution, the solute and solvent can be distinguished differently. The substance that dissolves in the solvent (liquid) is known as the solute and the substance that is added to the solute to dissolve it is known as solvent. The solution comprises both solute and solvent. The amount of solvent in a solution is larger than that of the solute.
There are two types of solution, aqueous and non-aqueous solutions. The solution in which the solvent used is water is known as aqueous solution. For example, a solution of salt and water is known as aqueous salt solution. A solution in which the solvent is ethanol, acids, acetone, etc. Are known as non-aqueous solutions. For example, Sulphur is dissolved in Carbon disulphide and not water.
The correct answer is Option D).

Note:
Aqueous solutions are further divided as strong electrolyte and weak electrolyte. On the basis of the dissociation of solute in water, these divisions are given. Strong acids and bases are considered as strong electrolytes and weak acids and bases are considered weak electrolytes.
