Question

Sugars are polar substances. Which action would make sugar more soluble in water?

A.
Increase the water temperature.
B.
Increase the surface tension of the water.
C.
Decrease the quantity of water.
D.
Decrease the polar nature of the sugar.

Answer 1

A.  increase the temperature of the water the higher the temp the more soluble

Answer 2

Answer: Option (A) is the correct answer.

Explanation:

When we increase he temperature then the molecules of sugar ans water will start to vibrate with more energy.

As a result, sugar molecules will spread widely into the water and thus, they will start to dissolve. So, sugar molecules being polar in nature will dissolve easily in polar solve (water) as like dissolve like.

Thus, we can conclude that the action of increasing the water temperature would make sugar more soluble in water.
