Question

Compare the titration curves of weak acid-strong base reactions with the curve for strong acid-strong base reactions. How are they similar? How are they different?

Answer 1

For strong acid and strong bas, addition of strong acid to strong base pH is slowly decreased until to reach equilvlent point, after reaching to euqivalent point there is steep in the curve, after that slow decrease observed.

Similarly for addition of weak acid to the strong base it is observed slow decrease of pH value in the curve, after reaching to euqivalent point there is small steep in the curve, but due to fomation of buffer, it resists in the decrease of pH value on further additon
