Solubility equilibria

Solubility equilibria describes the balance between a substance dissolving in a liquid and the crystals forming from that solution. When a soluble compound dissolves, it reaches a point where the rate of dissolving equals the rate of crystallization, creating a dynamic equilibrium. At this point, the amount of material dissolved stays constant unless conditions change (like temperature or pressure). This concept helps chemists understand how much of a substance can dissolve under specific conditions and predict whether a substance will stay dissolved or settle out as a precipitate.
