The solubility of a substance
The solubility of a substance decreases with the decrease in temperature
Let us take an example from our day to day life.
Akanksha planned to prepare lemonade for Shashank. She wishes to add ice to cool it. Two questions came up in her mind- Should she add ice to the lemonade before or after dissolving sugar and also, in which case is it possible to dissolve more sugar?
As we already know that the solubility of a substance decreases with the decrease in temperature. If Akanksha will add ice, the temperature of lemonade will decrease and dissolving sugar will be more difficult. Therefore, ice should be added after dissolving sugar.
