Completesolubilityoccurs when the solvent and solute have the samevalency.A metal of higher valency is more likely to dissolve in a metal with lower valency.

The solute and solvent should have similarelectronegativity. If the electronegativity difference is too great, the metals tend to formintermetallic compoundsinstead of solid solutions
