Question

Define solubility. How is it expressed?

Answer 1

It is defined as the maximum amount of a substance in moles, that can be dissolved at constant temperature to give one litre of its saturated solution.

It is expressed in moles per litre or moles per decimeter cube of a saturated solution at given temperature.

∴ molar solubility (mol/L) = `"solubility in g/L"/"molar mass in g/mol"`
