What is meant by solubility? how stirring and heating of solution affects solubility
Answers
The maximum mass of the solute that can be dissolved in 100 grams of the solvent at any given (specified) temperature is called its solubility.
We usually use a spoon to mix sugar in water or milk. The fact is that, stirring makes the solute dissolve faster in a solvent.
Solubility of a solute generally increases with increase in temperature. But for all substances this does not hold true. There are some substances whose solubilities first increases and then decreases with rise in temperature like Glauber's salt.
Answer:
Stirring increases the speed of dissolving
Stirring only increases the speed of the process - it increases move of the solvent what exposes solute to fresh portions of it, thus enabling solubility. As molecules in liquid substances are in constant move, the process would take place anyway, but it would take more time.
