Here's why:
* Solubility is defined as the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature. It's a property of the solute and solvent at a molecular level.
* Particle size refers to the physical dimensions of the solid solute. While smaller particles might dissolve faster due to increased surface area, the overall amount that can dissolve (solubility) remains the same.
Think of it this way:
Imagine a sugar cube and powdered sugar. Both are the same chemical compound (sucrose). If you add a sugar cube and powdered sugar to the same amount of water, the powdered sugar will dissolve faster because it has a larger surface area exposed to the water. However, the maximum amount of sugar that will dissolve in the water (the solubility) will be the same in both cases.
Factors that DO affect solubility:
* Temperature: Solubility usually increases with temperature.
* Pressure: For gases, solubility increases with pressure.
* Nature of the solute and solvent: "Like dissolves like". Polar solutes dissolve in polar solvents (like water), while non-polar solutes dissolve in non-polar solvents (like oil).
