how does methyl orange and phenolphthalein react with acids and bases?
Answers
Answer:
Methyl orange is a pH indicator frequently used in titration because of its clear and distinct color variance at different pH values. Methyl orange shows red color in acidic medium and yellow color in basic medium. Because it changes color at the pKa of a mid strength acid, it is usually used in titration for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of color change, but it has a sharp end point. In a solution becoming less acidic, methyl orange changes from red to orange and, finally, to yellow—with the reverse process occurring in a solution of increasin
Answer:
Indicator colors
In a solution that decreases in acidity, methyl orange moves from the colour red to orange and finally to yellow with the opposite occurring for a solution increasing in acidity. In an acid, it is reddish and in alkali, it is yellow.
