Quizplus · Accepted Answer

When Sonya adds sugar to the hot tea, it dissolves completely in the liquid, making it a solute. A solute is defined as the substance that is dissolved in the solvent (in this case, the solvent is hot water). A buffer, on the other hand, is a solution that resists changes in pH when an acid or base is added. Diffusion refers to the movement of particles from an area of high concentration to an area of low concentration.
