is a heterogenous mixture. Is it a true solution?
2. A solution that contains water as the solvent is called an aqueous solution. If carbon
disulphide is a solvent in a given solution, then the solution is called ______.
(aqueous solution, non- aqueous solution)
3. The solubility of common salt in 100g of water is 36g. If 20g of salt is dissolved in it,
how much more is required to attain saturation?
4. If two liquids are mutually soluble, they are called _______ liquids. (miscible, immiscible)
5. When sunlight passes through the window of a classroom, its path is visible. This is
due to _______of light. (reflection, scattering)
6. The particles in various forms are visible only under an ultramicroscope. A solution
containing such particles is called __________. (true solution, colloidal solution)
7. The number of components in a binary solution are/is _______ ( one / two)
8. The mixture of gases used by deep-sea divers is _______(helium-oxygen, oxygennitrogen)
9. Soil cannot store more nitrogen than it can hold. Hence soil is said to be in a state of
_________.(saturation, unsaturation)
10. In an endothermic process, solubility increases with _________ in temperature.
(increase, decrease)

⭐ Answer 1 ⭐

Chalk is not a true solution because condition for true solution is
- Particle should be homogeneous
- it's appearance must be clear and transparent
- Invisible to naked eye
_____________________________________

⭐ Answer 2 ⭐

If carbon disulphide is given solvent in the given solution then it is non - aqueous solution
Reason behind that is
-A solution in which water act as a solvent is called aqueous solution
- Any other liquid acts as a solvent is called non aqueous solution
