What is the significance of pH in titrations?

Here’s a explanation:

Significance of pH in Titrations

1. Shows Progress of the Reaction
   • pH changes as acid and base react.
   • It helps track how close the reaction is to completion.
2. Helps Find the Equivalence Point
   • The equivalence point is where acid = base.
   • A sudden change in pH shows this point clearly.
3. Helps Choose the Right Indicator
   • Different indicators change color at different pH values.
   • Knowing the pH at equivalence helps select a suitable indicator.
4. Determines Strength of Acid or Base
   • The pH curve shows if the acid or base is strong or weak.
5. Used to Plot Titration Curves
   • Measuring pH at each step helps draw a titration curve that shows how pH changes during titration.

In short:
pH is important in titrations because it helps find the endpoint, choose the right indicator, and understand the strength of acids and bases.
