When a reaction has reached equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. At equilibrium, the concentrations of reactants and products remain constant over time, but the reaction is still ongoing.
When a solution has gained as much solute as it can at a given temperature, it has reached the point of saturation. At this point, no more solute can dissolve in the solvent, and any excess solute will remain undissolved in the solution.
it doesn't depend on the temperature but depends on how much water was evaporated

As you add solute to a dilute If_you_add_solute_to_a_dilute_solution_what_does_the_solution_become, the solution becomes more concentrated until the solution has reached its saturation concentration. At the saturation concentration, no more solute can dissolve into the solution.Read more: If_you_add_solute_to_a_dilute_solution_what_does_the_solution_become
saturation
Such a solution is called is called unsaturated solution. In such a solution the salt dissolved hasn't reached the level of saturation. Also, more solute can be dissolved if temperature is increased after reaching the saturation.
The formula for the solubility product constant (Ksp) for a saturated solution of PbBr2 is Ksp = [Pb2+][Br-]^2. Substituting the given concentrations into the formula, we get Ksp = (2.5 x 10^-3)(5.0 x 10^-2)^2 = 6.25 x 10^-5. Therefore, the value of Ksp for PbBr2 at this temperature is 6.25 x 10^-5.
the rate of the forward reaction is greater than the rate of the reverse reaction.
