Question

A solution of a substance is said to be saturated if it cannot dissolve any more of the substance in it.
Bharti carried out an experiment to see what is the effect of temperature on a saturated solution.
She took 100 g of water in two beakers. She then dissolved sugar in one and salt in the other
slowly by adding small amounts each time and stirring, until the solution became saturated. The
temperature of the solution was maintained at 20 °C.
She repeated the same experiment at 60 °C and 100 °C. This is what she observed.
What can be concluded about the amount of substance dissolved to make a saturated solution, at
different temperatures of the solution?
A

As the temperature increases, more
amount of substance is needed.
B
As the temperature increases, same
amount of substance is needed.

C

As the temperature decreases, more
amount of substance is needed.
D
As the temperature decreases, same
amount of substance is needed.

Answer 1

Answer:

A solution of a substance is said to be saturated if it cannot dissolve any more of the substance in it.

Bharti carried out an experiment to see what is the effect of temperature on a saturated solution.

She took 100 g of water in two beakers. She then dissolved sugar in one and salt in the other

slowly by adding small amounts each time and stirring, until the solution became saturated. The

temperature of the solution was maintained at 20 °C.

She repeated the same experiment at 60 °C and 100 °C. This is what she observed.

What can be concluded about the amount of substance dissolved to make a saturated solution, at

different temperatures of the solution?

A

As the temperature increases, more

amount of substance is needed.

B

As the temperature increases, same

amount of substance is needed.

C

As the temperature decreases, more

amount of substance is needed.

D

As the temperature decreases, same

amount of substance is needed.
