Stirring makes sugar dissolve faster, but what is its effect on final solubility?
Answer and explanation
Correct answer: Generally final solubility does not change
Stirring continually brings fresh solvent into contact with the sugar surface and carries dissolved molecules away, so it increases the rate at which equilibrium is reached. At a fixed temperature and composition, however, the equilibrium maximum amount of sugar that can dissolve is generally unchanged. Stirring does not make water non-polar, convert sugar into gas, or create infinite solubility.
