We have dealt with the weak acid, so let's try an example with the weak base.
This weak acid dissolves limestone, forming the characteristic karstic relief which has received the name from district in Yugoslavia.
The ammonium ion is the weak acid and the ammonia is the weak(conjugated) base.
The weak acid is ammonium ion which has a pKA(see table)
So we could say, plus the logarithm of our conjugate base concentration divided by the weak acid concentration is equal to the pH.
So what's going to happen is the concentration of your weak acid is going to go down.
When the concentration of your conjugate base is equivalent to the concentration of your weak acid.
So if you just put some of this into some concentration, or you put some or your weak acid into a solution and you let it get to equilibrium.
A buffer solution contains not only the weak acid, but also a salt of that weak acid.
And that's because we had all of the conjugate base of the weak acid, which does make the solution more basic.
This 700 milliliters of our reagent must have the same number of moles as the number of moles of weak acid we started off with.
Weak acid waste and neutralized waste:
Weak acid dissociable cyanide' means cyanide and cyanide compounds that are dissociated with a weak acid at a defined pH;
So this can to be simplified to minus log of our Ka minus the log our weak acid concentration divided by its conjugate base concentration.
Let's say I have a bucket of aqueous solution, and it contains some weak acid in it.
When you have your concentration of conjugate base is equal to your concentration of your weak acid, this whole term turns into 0.
so a very weak base ánd a very weak acid.
De buffer formula: The weak acid is ammonium ion which has a pKA(see table)
that extra base will immediately be neutralised by the large amount of weak acid HA in that buffer.
Well, we must have added enough moles of OH at the equivalent point to cancel out all of the moles of the weak acid in whatever hydrogen was out there.
