Chapter Summary

In this chapter, you will learn about mixtures, solution, heterogeneous mixture, colloids and their uses, pure substances, compound, etc. A pure substance consists of a single type of particle. Mixtures contain more than one kind of pure form of matter. A solution is a homogeneous mixture of two or more substances.

FAQs

Q1: What type of mixtures are separated by the technique of crystallization?
Ans:
The technique of crystallization is used to separate solids from a liquid solution.

Q2: Differentiate between homogenous and heterogeneous mixtures with examples
Ans: The differences between homogenous and heterogeneous mixtures are tabulated below:

Q3: Classify each of the following as a homogeneous or heterogeneous mixture.
soda water, wood, air, soil, vinegar, filtered tea.

Ans:
The materials are classified as follows:

Q4. What is the definition of Saturated solution, Pure substance, Colloid and Suspension?
Ans:
Saturated solution: In a given solvent, no solute that can dissolve further at a given temperature is called a saturated solution.
Pure substance: When a single type of particle comprises an element, it is a pure substance. E.g., silver, gold.
Colloid: A solution in which the size of solute particles is more significant than a proper solution. These kinds of particles cannot be seen with our naked eyes. e.g., ink, blood.
Suspension: A heterogeneous mixture in which the solute particles are large enough to settle down, e.g., chalk-water, paints, etc.

Q5: To make a saturated solution, 36g of sodium chloride is dissolved in 100 g of water at 293 K. Find its concentration at this temperature.
Ans: Mass of solute (NaCl) = 36 g
Mass of solvent (H2O) = 100 g
Mass of solution (NaCl + H2O) = 136 g
Concentration = Mass of solute/Mass of solution x 100
Concentration = 36/136 x 100 = 26.47%
Hence, the concentration of the solution is 26.47%

Q6. Give some examples of pure substances or mixtures that we use in our daily lives?
Ans. Some examples of the substances we use in our daily lives.
Pure substances—Water, bread, sugar and gold.
Mixtures—Steel, plastic, paper, talc, milk and air.

Q7: Name the techniques used to separate the following:
(i) Butter from curd.
(ii) Salt from seawater
(iii) Camphor from salt

Ans: i) To separate butter from curd, a process called centrifugation is used. The process is governed by the principle of density.
ii) We can use the simple evaporation technique to separate salt from seawater. Distillation causes water to evaporate leaving solid salt behind, hence the production of salt.
iii) Sublimation can be used to separate camphor from salt as, during the phase change, camphor does not undergo a liquid phase.
