Question
During titration of acetic acid with aq. NaOH solution, the neutralisation graph has avertical line. This line indicates
Options
A.alkaline nature of equivalence
B.acidic nature of equivalence
C.netural nature of equivalence
D.depends on experimental proceeding.
Solution
In the titration of weak acid (CH3COOH) with a strong base (NaOH), there is a change in the pH value at the end point. But it is not sharp due to weak ionisation of CH3COOH. Due to the excess of free base steep rise in pH which is indicated by vertical line. Hence the vertical line in the graph indicateds. alkaline nature of equivalence.
