Summary:
- Ionic compounds have widely differing solubilities.
- Sodium chloride has a solubility of about 360 g per liter of water at 25°C.
- Salts of alkali metals tend to be quite soluble.
- Most ionic compounds that are considered to be insoluble will still dissolve to a small extent in water.
- These “mostly insoluble” compounds are considered strong electrolytes because whatever portion of the compound that dissolved also dissociates.
- Solubility product constant is equal to the mathematical product of the ions each raised to the power of the coefficient of the ion.
