Solubility Product Constant

Imagine you're trying to fit a group of friends into a small car for a road trip. Just like there's a limit to how many people can comfortably fit in the car, there's a limit to how much of a solid can dissolve in a solution before no more can fit, known as the solubility product constant (Ksp). In both scenarios, the car's capacity is like the Ksp, determining the maximum number of people (or particles) that can be accommodated before reaching saturation—once the car is full, any extra friends (or solid) simply can't fit.
