Here’s a explanation:
Significance of pH in Titrations
- Shows Progress of the Reaction
- pH changes as acid and base react.
- It helps track how close the reaction is to completion.
- Helps Find the Equivalence Point
- The equivalence point is where acid = base.
- A sudden change in pH shows this point clearly.
- Helps Choose the Right Indicator
- Different indicators change color at different pH values.
- Knowing the pH at equivalence helps select a suitable indicator.
- Determines Strength of Acid or Base
- The pH curve shows if the acid or base is strong or weak.
- 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.
