Advantages and disadvantages of the universal indicator solution

The advantages of the universal indicator solution are as follows.

• It is basically used to determine the estimated pH of a solution.
• Covers the entire pH range.
• One can use simple acid-base indicators just to identify the nature of a sample, whether it is a base or an acid. However, the universal indicator is used to determine the strength of a sample by indicating its pH value.
• Like the pH meter, there is no waiting time for the scale, it gives quick measurements.
• The universal indicator provides highly accurate results even with weak buffer solutions.
• If we follow the instructions on the label for storage, it has good stability.
• A wide range of colors are produced depending on the strength of the acid or base.
• This allows you to detect more things than a normal indicator.

The disadvantages of the universal indicator solution are as follows.

• When liquid pH indicators are used, the sample solution should preferably be clear and colorless.
• The pH meter is more accurate than the indicators
• The main disadvantage of the universal indicator solution is that it is not reusable.
• This can lead to environmental contamination.
• If the sample is contaminated, the result may be incorrect.
