Question

which is the most and least soluble at 298k ?​

Answer 1

(CH3)3N (Trimethylamine) is least soluble as there is no scope of H-bonding.

Answer 2

$CaCl_{2}$ is the most soluble and $Ce_{2}(SO_{4})_{3}$ is the least soluble at 293 K.

Explanation:

• Solubility is described as the property of a solid, liquid or gaseous chemical substance said to dissolve in a solid, liquid, or gaseous solvent.
• The solubility of a substance depends on the physical and chemical properties of the solute and solvent as well as temperature, pressure, and the presence of other chemicals (including changes in pH).
• In the given graph, at 25°C or 298k, $CaCl_{2}$ is the most soluble and $Ce_{2}(SO_{4})_{3}$ is the least soluble.
