Explain why the indicator changes colour during the neutralizing reaction |
|
Answer» Answer: An indicator shows whether an SUBSTANCE is a base or an acid but during a neutralisation reaction the colour change occurs due to the solution be neutral (i.e pH is 7). Explanation: INDICATORS are substances whose solutions change COLOR due to changes in pH. These are called acid-base indicators. They are usually weak acids or bases, but their conjugate base or acid FORMS have different colors due to differences in their absorption spectra. |
