What factors determine solubility of a substance?

Answer 1

There are several factors:

1) the polarity of the substance and the polarity of the solvent (like dissolves like).

2) the temperature of the solvent (for solids, the higher the temperature of the solvent, the higher the solubility -- sugar in hot tea dissolves more easily than in iced tea -- but often for gases, the solubility goes down at higher temperature -- and why soda goes flat when its warm).

3) Pressure also effects solubility. Notice CO2 will form bubbles when you open the cap of a soda can. A side note.....the size of the particles and whether or not you stir the solution will help speed up the dissolving process, but it will notchange the total amount that can be dissolved (whereas #1 and #2 do affect the total amount dissolved)

Lesson 4: Colligative Properties of Solutions:

a. Temperature and nature of solute and solvent

b. A large amount of solute

b. Molarity x Liters

d. 0.18M

b. Supersaturation

b. Disrupts Crystal formation of the solvent

d. 142 mL

Answer 2

1. the nature of solute/solvent (chemical composition, polarity)

2. temperature

3. pressure

4. stirring

5. surface area of the solute

6. some added compounds

7. amount of the solute

8. the geometry of the beaker

etc.

Answer 3

how much teaspoons of the substance dissolve in the water and if its ionic, polar colavent or non polar colavent

Answer 4

They include temperature and pressure, rate of mixing and the nature of the solvent.
