The equivalence point during a weak acid-strong base titration, the pH will be determined from ___.
1 answer:
Answer:
The pH will be determined from the equivalence point i.e. "greater than 7."
Explanation:
In the titration between the weak acid along with a strong base, the conjugate base of the weak acid will probably make the pH at the equivalence point which is greater than 7. Hence, an indicator is required to know the pH change at this range. Basically phenolphthalein is used as an indicator in this case. The weak acid will turn into bright pink. After this if excess of the hydrogen ions are added then the position of the equilibrium will be shifted to the left and make the indicator colorless.
