Question

36.Which of the following defines a saturated solution?

A. Less amount of solute than the maximum amount it can dissolve;

B. Small amount of dissolved solute in comparison to the amount of solvent.

C. The amount of solute in each volume of solution per milligram of solution

D. A solution that contains the maximum amount of solute dissolved by a given amount of solvent.

37. What solution is formed when there is a small amount of dissolve solute in comparison with the dissolving capacity of a given amount of solvent?

A. Saturated

B. Supersaturated

C. Unsaturated

D. Concentrated

38. You believe that a cup of water can still dissolve more juice powder. When is this happen, the water becomes (a)__________.

A. Supersaturated

B. solution

C. Soluble

D. Unsaturated

39. Which statement about the process of dissolving is TRUE?

A. Dissolving releases energy in the form of heat.

B. Solvent can be dissolved faster when stirring is applied

C. Applying heat often speeds up the process of dissolving particles.

D. Once a solute, such as salt crystal is dissolved in a solvent such as water, it can never return to its original crystal state.

40. Why does sugar have higher solubility in hot water as compared to salt?

A. The temperature of water limits the solubility of salt.

B. Sugar has smaller particle size compared to salt crystals.

C. Sugar and salt differ in nature that affects their solubility

D. The temperature of water does not affect the rate of solubility of salt

Answer 1

Answer:

36-C

37-C

38-A

39-C

40-A

Explanation:

36- The Amount of solute in solvent shows the saturation level of solution.

37- Less the amount of solute and more of solvent makes a solution Unsaturated.

38- When a solution does not allow solvent to melt it becomes Supersaturated.

39-Heat often broken the bonds Faster than usual stirring results in faster dissolving.

40- Temperarture Affect the solubility of salt in solvent i.e. why we heat water to dissolve more salt in it.
