A sodium hydrogen carbonate indicator is used to test for the presence of acids. It turns pink in the presence of an acid and yellow in the presence of a base. This color change helps to determine whether a solution is acidic or basic.

What is the mechanism of methyl orange in sodium carbonate and hydrogen chloride titration?

In the presence of sodium carbonate (base) and hydrogen chloride (acid) in a titration, methyl orange indicator changes color at the endpoint. At the beginning of the titration, the solution is basic due to the sodium carbonate, causing the methyl orange to appear yellow. As the acid is added and the solution becomes more acidic, the indicator changes to red at the endpoint when all the base has been neutralized by the acid.
