In the laboratory, Methyl Orange Disodium Salt is primarily used for:
- pH Indicator in Titrations: It’s effective for titrations in the pH range of 3.1 to 4.4, particularly in strong acid-strong base titrations.
- Acid-Base Indicator: Used to determine the endpoint of an acid-base reaction due to its distinct color change from red to yellow.
- Chemical Analysis: Helps in qualitative analysis to monitor pH changes in solutions and identify the presence of acidic or basic substances.
- Educational Purposes: Often used in educational labs to demonstrate acid-base reactions and indicator behavior due to its clear and simple color transition.
