A colorimetric method of pH determination is depicted to measure the pH of a liquid/ aqueous solution with the 0-01 pH unit accuracy. It is emphasized that the obvious pH measured by sulphone- phthalein indicators is not in the same amount as it gets electrometrically. The progress of glass electrodes, involved in the pH meter, has certainly made the electrometric method the most common way of pH measurement.
Since it can be applied in a highly diluted solution, colloids, and colored solution, where the indicators are inconvenient, in addition to these particular cases, the indicators provide some benefits, and it appears to us a mistake to regard that the electrometric method is a standard, and always the most precise method. The simple comparator is used, about 0-01 pH unit of reproducibility readily gives by an indicator.
Commonly asked questions on pH determination are as follows.
Which different methods are used for determination of pH?
Two types of methods are used for the determination of pH, the colorimetric method and the electrochemical method.
Can the colorimetric method be used to determine the pH of water?
Yes, we can use the colorimetric method used to determine the pH of water
Which method is the most accurate in pH determination?
The electrometric method of pH determination i.e. pH meter is the most accurate type of measurement and are broadly used.
