An acid base indicator is a chemical substance that has the ability to change color depending on the pH.
Indicator neutralization is the process of adding a neutralizing agent to an acid-base indicator solution to adjust its pH level. This helps to ensure that the indicator functions properly and gives an accurate color change at the desired pH.
Hydrogen itself is a gas. (H2) Hydrogen with other certain elements create acids.
Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
If phenolphthalein is added to HBr (hydrobromic acid), which is a strong acid, the phenolphthalein indicator will remain colorless because it only changes color in the presence of a base. Since HBr is an acid, it will not cause the indicator to change color.
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
Recreation of an indicator using an acid and a base involves mixing a colorless or faintly colored acid-base indicator with an acid to make the solution acidic (and change color) and then adding a base to neutralize the acid and return the indicator to its original color. This process demonstrates the reversible nature of acid-base indicators and how they can be used to visually indicate the presence of acids or bases in a solution.
This indicator changes his color.

The most appropriate indicator for a strong acid/strong base titration is phenolphthalein.
It is a substance(chemical or natural) which changes colour in the presence of an acid or base.
indicator
it is an indicator.
For the titration of a strong acid, the indicator typically used is phenolphthalein. Phenolphthalein changes color in the pH range of 8.2 to 10, which is suitable for titrating a strong acid with a strong base to determine the equivalence point.
