WebSep 14, 2024 · 1 Answer Sorted by: 3 Methyl orange (MO), as you know, is an acid-base indicator. The problem with those is that they do not distinguish between acidic and basic medium, but rather between different pHs. MO has a transition interval of 3.1-4.4, which means it's red below 3.1 and yellow over 4.4.
