Molar Solubility
Definition
Molar solubility is the number of moles of a substance (the solute) which can be dissolved per liter of solution before the solution becomes saturated.
Analogy
Imagine you're making lemonade. There's only so much sugar you can dissolve into your pitcher before it starts to collect at the bottom, no matter how much you stir. That maximum amount of sugar is like molar solubility - it's how much can dissolve before saturation occurs.
Related terms
Solvent: This is the substance that dissolves another substance (solute) to form a solution.
Saturation Point: This is when no more solute can be dissolved into solvent at given conditions.
Concentration: It refers to how much solute exists within an amount of solvent.
