We are ready to begin our next round of learning objectives
dealing with acid and base titration.
within these acid/base titrations
we are going to learn to calculate the pH
At various points
along the titration.
Now if you will think back to along the titration.
Now if you will think back to
what you have learning in the past
you have learned about acids and bases
titrations, most likely.
You might want to go back and review
what you have learned.
But one of the things you learned to do with
acid and base titrations is you are given
an acid
where you know the concentration and you are
trying to determine the concentration of
an unknown base.
You know the concentration
of a base and you are trying to determine the
pH or the concentration of an unknown acid.
And its a stoichiometry problem where you are
covering from the molarity and the volume of
the known or the standard solution
getting into moles of that
substance and determining
the moles of the other substance.
Within these units
that we are talking about here Within these units
that we are talking about here
and the next couple of learning objectives
we are going to look at how pH
changing during the course of this.
We are going to look at three types of titration.
We are going to begin
in this lesson with strong acids
and strong base titrations.
This will be learning objective number 5.
In learning objective number 6
we are going to have one of those
be weak. Either the acid will be weak
or the base will be weak. be weak. Either the acid will be weak
or the base will be weak.
We will never do calculations in which
both the acid and the base are weak.
There are very many equilibria involved
and it gets very complicated.
So we are going to do make sure that at least and it gets very complicated.
So we are going to do make sure that at least
one of those two will be strong.
