Question

reaction takes place in methyl orange end point?

Answer 1

methyl orange is a PH indicator frequently used in titration because of it's 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. unlike a universal indicator, methyl orange does don't have a full spectrum of color change ,but it a sharp end point.

Answer 2

The reaction that takes place in methyl orange endpoint is given in the image below.

Explanation:

• Methyl orange acts as an indicator to test whether the solution is acidic or basic.
• It has a sharp end point.
• It changes from red or orange if the solution becomes less acidic and further changes to yellow.
• A reverse colour occurs if the solution becomes more acidic.
• The endpoint for the acidity of methyl orange is $pH=3.7$.
• It is mainly used in the titration process.
• It is used in the titration of $\[N{a_2}C{O_3}\]$  with $HCl$.
• The end point reaction is given as:
