How do I know whether a solution of potassium nitrate in water is saturated?
Can you see crystals (of potassium nitrate) at the bottom of the flask?
If you can, then the solution is saturated.
Saturation describes an equilibrium condition as shown:
For highly soluble solutes such as potassium nitrate, equilibrium, i.e. saturation may be hard to reach in that the salt is mighty soluble in water, and a lot of solute must be added to reach equilibrium.
We could take an excess of salt (probably around half a kilo per litre of water) heat it up and bring all the salt into solution. Upon cooling, the salt may not precipitate, and remains in solution as a
And if the solution contains LESS solute than would be in equilibrium with undissolved solute, then the solution is termed
You may think I am being unnecessarily wordy, but the definition of
