Sugar cubes are added to a solution of water and lemon juice to make lemonade. The solubility of sugar is 200 g/100 g H2O at the temperature of the solution. What can be done to increase the rate of dissolution without affecting the solubility? Check all of the boxes that apply.

Stirring brings fresh liquid into contact with the sugar, and crushing the cubes exposes more sugar surface area; both speed up dissolution without changing the solubility. Warming or adding ice changes the solution’s temperature, which can affect sugar’s solubility. Increasing pressure has little effect on the solubility of a solid in a liquid and does not meaningfully speed its dissolution.
