Methyl Orange Disodium Salt is a synthetic dye commonly used as a pH indicator in titrations. It appears orange in neutral solutions and changes to yellow in alkaline conditions, providing a clear and distinct color transition. This dye is valued for its sharp and easily distinguishable color change around pH 3.1 to 4.4.
Key Characteristics:
- Appearance: Orange to yellow solid or powder.
- Solubility: Soluble in water.
- Color Change: Red to yellow as pH increases from acidic to slightly basic conditions.
Uses of Methyl Orange Disodium SaltÂ
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.
