We note that the solubility of a salt depends on the temperature.
00:05
In general, the higher the temperature is, the more soluble the solid solute.
00:12
So in this problem, we're given with the solubility of rock salt at 30 degrees celsius to be equal to 40 grams of salt per 100 grams of solvent, which is water.
00:27
So this is again at temperature of 30 degrees celsius.
00:32
Now we want to identify whether a solution that contains 10 grams of salt in 25 grams of water is saturated, unsaturated or super saturated.
00:46
So we will define later what those terms mean.
00:50
So for a saturated solution, the amount of salt that can be dissolved in 100 grams of water is given by the solubility.
01:01
So that means 40 grams of salt per 100 grams of water.
01:06
Now if the amount of the salt is lower than 40 grams, so that means if you have 100 grams of water and that you have less than 40 grams of salt in it, that means the solution is unsaturated...
