Question

Solubility of salts in water is temperature dependent. consider the solubility curve of the salts seen here. which salt's solubility changed the least from 0 - 100oc; which salt's solubility changed the greatest amount from 0 - 100oc?a)both changed the same amount.b)sodium chloride changed the least; potassium nitrate changed the most.c)potassium nitrate changed the least; potassium iodide changed the most.d)potassium chlorate changed the least; potassium iodide changed the most.

Answer 1

the answer is B: sodium chloride changed the least; potassium nitrate changed the most.

Answer 2

B: sodium chloride changed the least; potassium nitrate changed the most.

Step-by-step explanation:

Sodium chloride barely changed its solubility, while potassium nitrate increased its solubility from less than 20 g/100 mL to more than 150 g/100 mL
