Alright, so if you have a solution that has a low concentration of hydrogen ions, then it means the ph of the solution, which is determined by the concentration of hydrogen ions will be, you know, high, because if the concentration of hydrogen ions is low, then the ph would be high, that is ph greater than 7.
00:32
Then b, we have containing a weak acid dissolved in water.
00:39
Remember, it's an acid that does not completely dissociate in water, meaning that it doesn't release all of its hydrogen ions, okay? so no, or let's say less, hydrogen ions dissociated in water.
00:59
Therefore, concentration of hydrogen ions will be in the solution, will be very low, and the ph, again, will be greater than 7, okay? c is, contains a strong base dissolved in water.
01:14
So strong base is dissolved in water, a strong base is just that substance that completely dissociates in water, releasing almost all of the hydroxyl ions, okay? so therefore, again, it will make the ph greater than 7...
