Saturated,Unsaturated and Supersaturated Solutions

Q. A saturated solution is a solution in which:

1. The components of the solution can be separated only by chemical methods
2. More substances can be dissolved in the solution without heating
3. No more amount of a substance can be dissolved
4. More substances can be dissolved in the solution on cooling

Q. When no more solute can be dissolved in a solution at a given temperature, then such a solution is called a/an ___ solution.

Q.

Harry Potter wanted to make a supersaturated solution of dragonwood in his potions class. Select from the following which would allow him to make one.
Note: Cauldron is just a vessel.

1. Reduce the volume of water in the cauldron.
2. Increase the temperature of water.
3. Increase the pressure of the gas.
4. Reduce the pressure of the gas.

Q.

A solution in which no more solute can be dissolved in solvent is known as:-

1. Dilute solution

2. Unsaturated solution

3. Supersaturated solution

4. Saturated solution

Q.

Harry: Hey Hermione, does a supersaturated solution made by increasing temperature stay like that forever when left idle in a room?
Hermione gave him a blank look thinking Harry was an idiot.

Why did Hermione think Harry was an idiot?

1. Because supersaturated solutions stay forever once made.
2. Because a supersaturated solution can be formed for a limited time only.
3. Because a solution can never be supersaturated. It is an idealistic phenomenon.
4. Because all solutions are supersaturated.

Q.

A solution is said to be ___ if it can hold more of the solute in the given solvent at that temperature.

Q. The stage at which no more solute can be dissolved in the given solvent is called point.

1. saturation
2. critical
3. dissolution

Q. Which amongst the following is formed when two or more elements are chemically bonded together?

1. Compound
2. Mixture
3. Element
4. Atom

Q. Which of the following is true for a homogeneous mixture?

1. Particles are separable
2. Uniform composition
3. Non-uniform composition
4. Particles are visible

Q. When no more solute can be dissolved in a solution at a given temperature, then such a solution is called a/an:

1. Unsaturated solution
2. Supersaturated solution
3. Saturated solution
4. Subsaturated solution
