Answer : In lower concentrations, salts generally dissolve.
Explanation :
As we know that the solution is made by the combination of the solute and the solvent.
Solute is the substance which dissolved in the solvent and the solvent is the substance or liquid that dissolves the solute.
In the lower concentrations, the amount of solute is less than the solvent that means the more amount of solute can be dissolves into the solvent.
In the higher concentrations, the amount of solute is more than the solvent that means the more amount of solute can not be dissolves into the solvent.
Hence, in lower concentrations, salts generally dissolve.
