Question

Q1. WHAT IS NEUTRALIZATION? WHICH INDICATOR
IS USED FOR THIS PURPOSE? HOW DOES THIS
INDICATOR HELP? WRITE THREE EXAMPLES OF
NEUTRALIZATION REACTION.
​

Answer 1

Answer:

• Neutralization indicators, or acid-base indicators or pH indicators, are auxiliary reagents added to the titrand solution in order to detect the equivalence point in acid-base titrations. ... Tournesol, a natural pigment extracted from some blue-green lichens, was the first pH indicator to be used (1850).
• Phenolphthalein
• The indicator which is generally used to observe neutralization reaction is Phenolphthalein. Phenolphthalein is chosen because it changes color in a pH range between 8.3 – 10.
• Hint: The neutralization reaction is the one in which an acid reacts with an equimolar amount of base to give salt and water. The example could be a reaction between any strong acid and a base. The sodium chloride formed is a result of neutralization reaction.

Answer 2

reaction in which acid and base react to form salt and water is known as Neutralization reaction. It's ph is 7
