Product Description
Methyl Orange is an azo dye indicator supplied as an orange crystalline powder or as a ready indicator solution. It is widely used in acid–base titrations due to its sharp and distinct color change from red in acidic medium to yellow in alkaline medium. Ideal for endpoint detection in strong acid vs. weak base titrations.
