Sagot :
The acids do not completely dissociate in water. So, they tend to form a buffer system. Above pH 3.5, the concentration of the conjugate base is more than the concentration of the acid.
Weak acids:
- These are the acids that do not completely dissociate in water. So, they tend to form a buffer system.
- Buffers are used to resist a slight change in pH. The pH is equal to the pKa of the solution at equivalence.
- At equivalence, the concentration of weak acid and its conjugate base is equal.
After the equivalence point, the concentration of the conjugate base is more than the concentration of the acid.
Therefore, after 3.5 the concentration of the conjugate base is more than the concentration of the acid.
