Question

If a bowl of soup saturated with salt at room temperature is heated to a boil, is it still saturated? Explain why or why not.

Answer 1

Actually it pretty much still is saturated with salt at the boiling point, which is just a tad over 100C. That's because the solubility curve for NaCl isn't much of curve. It's more of a nearly horizontal line.

Nonetheless, the solubility curve for NaCl does drift upward slightly as T increases, and so by the time the boiling point is reached, it won't be saturated.

Answer 2

No it is still not saturated.

Step-by-step explanation:

A saturated solution is one in which we cannot add solute further (to get dissolved completely). In a non saturated solution we may add further solute which gets dissolved in it.

When we heat a solution, the solubility of a solute generally increases.

So if we have a soup of saturated salt at room temperature, on boiling there is chance that the soup is no longer saturated and we can add some more salt to it to make it saturated.
