Question

An example of solid in non aqueous solvent is:
A) Sugar in ethanol
B) Blood
C) Starch
D) Sugar sol

Answer 1

Solvent is considered as the substance which dissolves another substance so that the formation of solution takes place. A solvent is a chemical substance which dissolves other chemical substances so that a formation of solution of homogeneous mixture can take place. Solvents are usually liquid but not necessarily liquid. The solvent is the component present in the solution at largest amount.

Complete answer:
The solutions which we obtain by dissolving a solute in any other solvent other tan water then it is known as a non aqueous solution. The non aqueous solvents usually have low dielectric constant. There are different types of non aqueous solvent are aprotic solvent which have neutral charge and are inert in nature. The protophilic solvent is basic in nature and on reaction with acid the formation of solvated protons takes place. The other is protogenic solvent which is acidic in nature. The other is amphiprotic solvents which have protophilic and protogenic properties.
So for option ‘a’, sugar in ethanol in which the sugar is a solid solute and the solvent ethanol is a non aqueous solvent so it is the example of solid in a non aqueous solvent. So option a is the correct answer.
Blood and starch are colloidal solutions. It is a colloid because the size of the blood cell is between 1nm to 100nm. Sugar sol is a true solution because it is a homogeneous mixture which has uniform properties throughout.

Hence, the correct option is (A) .

Note: The particles of true solutions and colloidal are very small to be seen through naked eyes. The particles of solute in true solution do not settle when they are left undisturbed. Colloidal particles tend to pass and are filtered through parchment paper or animal membranes.
