What colour is methyl red in alkali?
When you add methyl red to a solution it will indicate it's pH. When the pH is under 4.4 the solution will appear red in color (or maybe pink). When the solution is above pH 6.2 it will appear yellow in color. Any where in between will appear orange. So if you add base to a red/pink or orange solution it will turn yellow as the solution becomes more basic. But I honestly do not know th actual chemical reaction that causes the indictor's color change.
