when potassium nitrate is dissolved in water to a cooling notes . one can then conclude that:
a) the solubility of the salt increases with temperature .
b ) the salt is poorly dissociated in water.
c ) the salt solubility decreases with temperature .
d ) the salt dissociated in water is very
e) there is a lowering of the freezing point of water.

c) the salt solubility decreases with temperature.

Salts usually dissolve in water at a given temperature. When water cannot dissolve anymore salt at that same temperature, it is known as a saturation point. With most substances the solubility increases with increase in temperature. Same is the case for a salt like potassium nitrate. With increase in temperature the ability of it to dissolve in water increases. And so with decrease in temperature, the solubility decreases.

The correct answer is:   bri hope this answer was ! : )
