Select the synthetic indicator from among the given options.
Show answer & explanation
Correct answer: A
Explanation
The correct answer option 1 i.e. Methyl orange.
The synthetic indicator among the given options is Methyl orange.
Methyl orange is a synthetic pH indicator commonly used in titrations because of its clear and sharp color change between acidic and neutral/basic solutions. It changes color from red in acidic solutions to yellow in neutral and basic solutions. Unlike natural indicators such as turmeric, cabbage juice, and litmus solution, which are derived from plants, methyl orange is chemically manufactured in laboratories. Synthetic indicators provide more consistent and precise results in chemical analysis, making them preferable in scientific and industrial applications. Natural indicators, while useful, can be less reliable due to variability in their composition.
