This change in color indicates a chemical reaction taking place in the test tube. The specific reaction that caused the color change would depend on the substances present in the test tube and their chemical properties.

What is methly orange?

Methyl orange is a pH indicator frequently used in titrations. It is often chosen to be used in titrations because of its clear colour change. Because it changes colour at the pH of a mid-strength acid, it is usually used in titrations for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of colour change, but has a sharper end point. Check out the Related Link for more details.

What is the colour change observed as the end point is approached when borax is titrated against a solution of HCl using screened methyl orange indicator?

When titrating borax with HCl using methyl orange indicator, the color changes from yellow to orange as the end point is approached. This color change is due to the change in pH from basic (yellow) to acidic (orange) as the titration progresses.


What is the name of the chemical which changes colour when it is mixed with acids or alkalis?

Why does the universal indicator change colour it had put vinegar?

Universal indicator changes color when exposed to vinegar due to the change in pH. Vinegar is acidic, which causes the indicator to shift to a color that corresponds to that level of acidity.

In the estimation of sodium carbonate you use methyl orange as an indicator?

Methyl orange changes color from red to yellow at a pH of around 4.4 to 3.1. In the titration process, the color change indicates the endpoint of the reaction between the sodium carbonate and the acid being used. This allows for precise determination of the amount of sodium carbonate present in the solution.
