Why is phenolphthalein used in titration instead of methyl orange?
Likewise, people ask, why is methyl orange used in titration?
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 pH of a mid strength acid, it is usually used in titration for acids.
One may also ask, what indicator can be used instead of phenolphthalein? This will be explored further down this page. Phenolphthalein is another commonly used indicator for titrations, and is another weak acid. In this case, the weak acid is colourless and its ion is bright pink.
Also asked, why is phenolphthalein used in titration?
A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions. Titration: Titration of an acid-base system using phenolphthalein as an indicator.
What is the Colour change of phenolphthalein?
Phenolphthalein is naturally colorless but turns pink in alkaline solutions. The compound remains colorless throughout the range of acidic pH levels but begins to turn pink at a pH level of 8.2 and continues to a bright magenta at pH 10 and above.
