Which indicator is used in titration for strong acid?
It depends on the base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator.
Indicators used in acid base titration?
It depends on the acid or base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator. For weak acid vs. strong base, phenolphthalein can be used as indicator.
Why indicator is being used in titration?
An indicator is so you can see when the end point of the reaction occurs, or when the reaction is complete. This can be an acid-base indicator such as methyl orange which determines the end point with a colour change.
What colorimetric pH indicator should you use for ammonia and hydrochloric acid titration?
Since the titration is between a strong acid and a weak base, methylorange should be suitable as the equivalence point is around pH 5. The K of the indicator should be equal to the pH at the end point. Methyl orange is that indicator
What is a substance that changes color when mixed with an acid or base?
acid base indicator or pH indicatorSome examples of acid base indicators are: gentian violet, malachite green, thymol blue, methyl yellow, bromophenol blue, congo red, methyl orange, screened methyl orange, bromocresol green, methyl red, methyl purple, phenolphthalein, indigo carmine, hydrangea flowers, anthocyanin, litmus, red cabbage, and purple cauliflower.
What colour indicator is toothpaste in methyl orange?
Yellow because toothpaste is base
Which indicator is used in titration for strong acid?
It depends on the base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator.
Where can you buy methyl orange indicator?
We can buy methyl orange(indicator) from scientific stores or chemical stores.

Why is methyl red indicator more suitable?
Methyl red is used as a pH indicator or for the identification of some bacteria.
When you add an acid to an alkali it changes to a neutral which colour change would this show with an indicator?
It depends on the indicator and there are quite a few. Methyl Red, Methyl orange and Phenolphthalein are 3 such acid-base indicators. If phenolphthalein is used as the indicator and added to the base it would immediately turn red/pink. As acid is titrated in, the red/pink will disappear and go colorless.

What are some other ways that acid base titrations are used?
Acid-base titrations are usually conducted with an indicator. Indicators are used to measure the end point precisely. Some of common indicators are methyl red, methyl orange and bromothymol blue.
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
In the estimation of sodium carbonate you use methyl orange as an indicator?
yes .. we use methyl orange as an indicator ... when added it gives a straw yellow colour
