Which of the following statements about solubility is true? Solubility is the same for a given solute in all solvents. When a solution is saturated, equilibrium is reached. When a solute reaches its solubility limit in a solvent, the dissolution process completely stops. When a solute has large solubility in a solvent, the two compounds are miscible to each other.
