Study Notes

Solubility

Polar compounds dissolve in polar solvents, this is called the "like dissolves like" rule.
Nonpolar compounds dissolve in nonpolar solvents.
Solubility can be expressed as soluble (S) or partially soluble (PS) or insoluble.

Density

Density is defined as mass per unit volume, and is typically measured in grams per millilitre (g/mL).
The density of water at 25°C is 0.9970 g/cm3.
1 mL is equivalent to 1 cm3, so these units can be interchanged.
