Solubility of salts in water is temperature dependent. consider the solubility curve of the salts seen here. which salt's solubi
lity changed the least from 0 - 100oc; which salt's solubility changed the greatest amount from 0 - 100oc?

Answer:
sodium chloride changed the least; potassium nitrate changed the most.
Explanation:
In the picture attached, the missing solubility curve of the salts is shown.
Sodium chloride changed the least because the solubility at 100 °C is very similar to the solubility at 0 °C.
Potassium nitrate changed the most because the difference between the solubility at 100 °C and the solubility at 0 °C (which is approximately equal to 243 - 13 = 230 g of potassium nitrate per 100 cm^3 of water) is the greatest of all the differences of solubilities for any compound.
