Question

a) A salt whose solubility increases rapidly with temperature?
b) A salt whose solubility increases gradually with temperature?
c) A salt whose solubility increases slightly with temperature?
d) A salt whose solubility initially increases then decreases with rise in temperature?

Answer 1

Answer:

The solubility of most salts increase with temperature.

As temperature increases the kinetic energy of molecules increases and their solubility also increases.

To give an example we can give an example of a salt.

The salt we can give its example is :

Sodium Chloride.

Answer 2

Explanation:

All four substances have higher solubility at higher temperatures in the range from 0 to 100 degrees Celsius.

KBr and KCl both roughly double their solubility from 0 to 100 degrees Celsius.

To me the question does not make sense.
