Thank you for the opportunity to help you with your question!
We add solutes to water rather than adding water to the solute because solute is the minor component of the solution and water is the major component.There is a really simple reason for this: the solute will dissolve more readily into a dilute solution. If you add the solvent to the solute, you immediately have a saturated solution because there is more solute than solvent. This is not only difficult to stir.mix, it means that as more solvent is added, the solid solute has to disperse from a region of high concentration, which usually takes more time. The other negative factor is that if the solute is hygroscopic and the solvent is water, the solute may form a hard-to-dissolve clump when the first water is added.
