Solution is the liquid mixture in which the minor component (the solute) is dissolved in the major component (the solvent). So, when Pinki made lemonade by dissolving lemon juice and little sugar in water, it means lemon juice and sugar are the solutes, Water is the solvent, and lemonade is the solution.
