Question

You prepare a solution and you add 50 g of potassium nitrate to 100 ml of water at 50 ° C. What type of solution are you prepared?

Ammonia is a gas. Describe what happens to the solubility of ammonia when the temperature rises from 20 ° C to 80 ° C.

What two substances which have the same solubility at 28 ° C?

Answer 1

We much prefer one question per post.
a) and b). Both require a knowledge of the solubility. I suggest you look on the web for that information. I don't have it in any of my references and I don't keep that kind of info in my head.

c). The solubility of most gases decreases with increasing T.

Answer 2

d needs clarification.

Answer 3

Saturated
