Question

Depending upon the nature of the solute and the solvent there are nine type of solutions. A solution

in which water acts as the solvent is called an aqueous solution while the one in which any other

liquid acts as the solvent is called a non-aqueous solution. Depending upon the amount of solute

present in a solution, it can be called a dilute, concentrated or saturated solution. The concentration

of solid may be expressed as mass by mass percentage or mass by volume percentage.

i) Which of the following is a non-aqueous solution?

(a) Iodine in alcohol (b) Common salt in water (c) Sugar in water (d) Alcohol in water

ii) 40g of common salt are dissolved in 320g of water, the mass by mass percentage of the solution is

(a) 11.1% (b) 15.2% (c) 13.4% (d) 12.5%

iii) Type of solution in which amount of solute is higher than solvent is called

(a) dilute (b) aqueous (c) concentrated (d) colloidal

iv) 2.5g of a solute are dissolved in 25g of water to form a saturated solution at 298K. The solubility of

solute at this temperature is

(a) 15g (b) 12.5g (c) 10g d) 20g

v) Which of the following is a pure substance?

(a) Kerosene oil (b) Steel (c) Sodium chloride (d) Valcanized rubber​
