Answer» 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.
