Why is a universal indicator not used in titration?

The universal indicator is not used in titration because they have different pH ranges. It becomes difficult to determine the exact pH of the solution. Therefore, universal indicator is not used in titration.

Why is the use of an indicator not suitable for determining the equivalence point of a weak acid weak base titration?

A solution of a weak acid cannot be titrated with a weak base using an indicator to find the end-point because the pH change is too gradual close to the equivalence point.

How do you know if a indicator is suitable for a titration?

When selecting an indicator for acid-base titrations, choose an indicator whose pH range falls within the pH change of the reaction. For example, in the titration of a strong acid with a strong base, the pH quickly changes from 3 to 11.

Is universal indicator reliable?

The 30 randomly effectiveness tests of the universal indicator from native plants has 100 percent of accuracy.

Why is the universal indicator better than litmus?

Because universal indicator can turn a range of different colours, it is helpful in specifying the strength of an acid or alkali. As a result, it gives a more precise result than litmus paper, which only tells you if a solution is an acid or alkali.

Which of these indicators is most appropriate for determining the end point of a titration involving a mid strength acid?

When performing the titration, it is best to position the tip of the buret: so that it just touches the bottom of the Erlenmeyer flask. Which of these indicators is most appropriate for determining the end point of a titration involving a mid-strength acid? Phenolphthalein.

Why doesn’t the indicator affect the titration results?

In all titrations, the amount of indicator added to the solution to be titrated is just a small amount. This is because even at very low concentration…

Why do we use universal indicator?

Universal indicator is supplied as a solution or as universal indicator paper . It is a mixture of several different indicators. Unlike litmus, universal indicator can show us how strongly acidic or alkaline a solution is, not just that the solution is acidic or alkaline.

What is universal indicator for what purpose it is used?

A universal indicator is a pH indicator made of a solution of several compounds that exhibits several smooth colour changes over a wide range of pH values to indicate the acidity or alkalinity of the solution. They are used to indicate the acidity and alkalinity of the solution by colour change.

Why is the universal indicator more useful than other indicators?

A universal indicator is better than an ordinary indicator as it not only shows whether the solution is acidic or basic but also gives the pH values (approx.) by giving a wide range of colours corresponding to different pH values.
