DEVELOPMENT OF ACID-BASE INDICATOR FROM FLOWER

The Lewis theory provides the broadest definition of acids and bases, and correctly predicts the acidic or basic properties of many substances that are missed by the other two theories; however, the Lewis theory does not explain the relative strengths of acids and bases, nor does it correctly predict the rates of acid-base neutralization reactions.

Acid Base Indicators Ph Titration scribd.com

Acid-Base Titrations and use of indicators:The process of acid base titrations is accompanied by a change in pH. .A plot between pH of the solution during titration and the amount of acid (or alkali) added from a burette is called a titration curve. Indicators are frequently employed in detecting endpoints in acid-alkali titrations.
