1) Solubility is the maximum amount of a solute that can dissolve in a given amount of solvent at a specific temperature and pressure, forming a saturated solution.
2) In general, for most solid solutes, solubility increases as temperature increases. For gases, solubility typically decreases as temperature increases.
3) Ce₂(SO₄)₃
4) 50 grams
5) 39 grams
6) 120 grams
7) NaCl
8) Unsaturated
9) Saturated
10) 10 grams
11) 10 grams
12) Ce₂(SO₄)₃ and NH₃
13) KI
14) KClO₃

a) At 80°C, the solubility of KCl is approximately 50g per 100g of water. Therefore, only 50g of the 120g KCl will dissolve, and 70g will remain undissolved at the bottom.
b) At 50°C, the solubility of NaNO₃ is approximately 115g per 100g of water. Therefore, 115g of the 130g NaNO₃ will dissolve, and 15g will remain undissolved at the bottom.
