Phenolphthalein is used in NaOH and oxalic acid titration to get neutralisation point.
Phenolphthalein is used as the indicator when comparing a strong base to a weak acid, such as acetic acid.
8.3–10.0 for phenolphthalein.
A dramatic pH change from 4.7 to 9.0, close to the Neutralisation mark, is observed in the weak acid versus strong base titration. Indicator Phenolphthalein is used in this case.
A chemical process known as neutralization occurs when an acid and a base interact quantitatively. When a reaction occurs in water, neutralization ensures that there aren't any extra hydrogen or hydroxide ions in the process's solution. The neutralization point designates that location.
