1. I Need A neat and clear hand drawn graph of titration 1 (NaOH
and HCl) including all of.
2. a clear and descriptive title
3. all axes correctly labelled (must have units)
4. all relevant data and outliers clearly shown.
From graph 4 (strong base/weak acid) estimate the pKa
value for the weak acid (acetic acid). This can be obtained from
the point at which half the acid has been neutralised i.e. halfway
to the end point. At this point pH = pKa. Mark this point and
record the value on your graph.
