What color does methyl orange indicator turn in an acidic medium?
A. Yellow
B. Pink or Red✓ Correct Answer
C. Blue
D. Colorless
💡 Solution & Explanation
Methyl orange indicator changes its color from yellow in basic or neutral solutions to pink or red in acidic solutions, with a pH transition range typically between 3.1 and 4.4. Other indicators like phenolphthalein remain colorless in acid and turn pink in alkali. This property makes methyl orange a reliable visual marker in acid-base titrations involving strong mineral acids.
