A salt solution can be prepared by mixing adding a solute which is salt to a solvent whereby the solute dissolves totally in to the solvent to form a solution
That is not quite correct.
Solute-solvent solutions, respectively, of acid and base - or vice versa - when in ionic proportion to achieve neutrality, results in a salt solution.
