1. The volume occupied by a single gas in a mixture at the same temperature and pressure is referred to as the single-gas volume.
a) Absolute volume
b) Partial volume
c) Total volume of a gas mixture
d) None of the mentioned
Answer: b
Explanation: At the same temperature and pressure, the volume occupied by a single gas alone in a combination is a portion of a volume.
2. The pressure that a single component in a gaseous mixture would exert if it existed alone in the same volume as the mixture and at the same temperature as the mixture is referred to as.
a) Absolute pressure
b) Partial pressure
c) Total pressure of a gas mixture
d) None of the mentioned
Answer: b
Explanation: Partial pressure is the pressure exerted by a single component in a gaseous mixture if it exists alone in the same volume.
3. _________________ obeys Raoult’s law in all stages of concentration.
a) Ideal Solution
b) Non-Ideal solution
c) Real Solution
d) None of the mentioned
Answer: a
Explanation: At all concentration levels, Ideal Solution follows Raoult’s law.
4. When two perfect solutions with volume V each are combined, What is the volume of the solution as a result?
a) V
b) 2V
c) Greater than 2V
d) Less than 2V
Answer: b
Explanation: When two perfect solutions are mixed, there is no change in volume.
5. The heat of solution or mixing has a negative side.
a) Heat of solution
b) Heat of dissolution
c) Heat of reaction
d) Heat of mixing
Answer: b
Explanation: The heat of solution or mixing has a negative side. Dissolution’s heat.
6. A solution made up of numerous components in which each component’s property is the weighted sum of its separate properties. The answer is
a) Ideal Solution
b) Non-Ideal solution
c) Real Solution
d) None of the mentioned
Answer: a
Explanation: An ideal solution is made up of numerous components, each of which has a property that is the weighted sum of the attributes of the others.
7. What is an example of camphor in N2 gas?
a) Solid in gas solution
b) Gas in gas solution
c) Solid in liquid solution
d) Liquid in gas solution
Answer: a
Explanation: Solid in gaseous solution is an example of camphor in N2 gas. Gaseous solution refers to a solution in which the solvent is gaseous. Other gaseous solutions include air (O2 + N2), iodine vapors in air, humidity in air, and so on.
8. What happens when a solute crystal is added to a supersaturated solution?
a) It becomes a colloidal solution
b) The solute dissolves in the solution
c) The solution desaturates
d) The solute precipitates out of the solution
Answer: d
Explanation: Solute particles leave the solution and form a crystalline precipitate when a solute crystal is added to a supersaturated solution. Seeding refers to the addition of the solute crystal.
9. Which of the following options is not a viable option?
a) Brass
b) Bronze
c) Hydrated salts
d) Aerated drinks
Answer: d
Explanation: A solid solution is a one- or more-solute solid-state solution in a solvent. Solid solutions include brass, bronze, and hydrated salts. Liquid solutions include aerated beverages.
10. What makes a solution?
a) Solute and solvent
b) Solute and solute
c) Solvent and solvent
d) None of the above
Explanation: The solution is made up of two components that is solute and solvent.
