Question

Lemonade is prepared by mixing lemon juice and sugar in water. You wish to add ice to cool it. Should you add ice before or after dissolving sugar? In which case would it be possible to dissolve more sugar?

Accepted Answer

We should add ice to the lemonade after dissolving sugar in it. When ice is added after dissolving sugar, we will not be able to dissolve more sugar because ice decreases the dissolving power of water as the temperature decreases due to the addition of ice. Solubility is the maximum amount of a substance that can be dissolved in $100 grams$ of water at a given temperature. The solubility of a substance decreases on cooling. Hence, we must add sugar to lemonade, before we are adding ice.
