And then plus a hydroxide ion.

I guess on the other side, you could add more hydroxide and then you would have more OH concentration, and maybe a

Well the little hydroxide ion is going to pop off.

You produce hydroxide and some sodium cations.

To OH minus plus sodium cation.

Remember, hydroxide is a strong base.

If you put them in water, the hydroxide pops off.

Or are you creating hydroxide or not?

As I slowly add hydroxide, it's going to increase the pH.

So it increases the hydroxide concentration.

The hydroxide ion got disassociated, and it becomes a little bit fungible right here.

When you increase the amount of OH, you would decrease the pOH, right?

Since it gave away one of the hydrogens now it's just OH minus.

So the surrounding water molecule is OH minus aqueous.

And a base is something that increases your hydroxide concentration in water.

So this guy, he had this nice little relationship with this hydroxide ion.

And so on this axis, I'm going to slowly add more and more of this hydroxide.

I'm considering this a base, which means that it's going to increase the concentration of OH.

So this is the sound of the O H stretch, translated into the audible range.

So I must have added 1 mole of hydroxide to get to this point.

Arrhenius's definition, the base is something that creates hydroxide ions, or anions in water.

So if you increase OH, you're decreasing pOH, and you're increasing pH.

So this, the OHs are going to go down initially, but then you have this reserve of weak base here.

So you're going to have more of our weak base turning into a weak acid and producing more OH.

So you all of a sudden immediately increase the quantity of OHs by essentially the number of moles of sodium hydroxide you're adding, and you'd immediately increase the pH, right?

So if I just did NaOH in an aqueous solution so that's just throwing it in water that disassociates completely into the sodium cation and hydroxide anion.

H2O, disassociating in itself, really, into a hydrogen ion in an aqueous solution plus a hydroxide anion in an aqueous solution or a negative ion.

But just to get back to the point, if you just did this in water, you immediately get a super high pH because the OH concentration goes through the roof.

This is going to lower the pH, but then you have more OH that could be produced as this guy grabs more and more hydrogens from the water.

Look, if we have a stressor that is decreasing our overall concentration of OH, then the reaction is going to move in the direction that relieves that stress.
