pH is the determination of hydrogen ion concentration in a sample solution. It is measured on a negative logarithmic scale from pH 0.0 to pH 14.0. The acidic pH has a below 07.00, basic has a pH 07.00 to pH 14.00 and a pH of 7.00 is considered neutral.
Litmus paper is considered as the most recognizable pH paper, it used to check the solution acidic or basic, it is available in three types red litmus paper (indicates blue in basic), blue litmus paper (indicates red in acidic) neutral litmus (indicates red in acidic, blue in basic). To determine the precise pH of a solution, you will require a pH test paper which is more specific compared to a litmus strip. There are several advantages to using pH papers and strips.
The advantages of a pH paper:
- They are rapid and simple to use than pH meters.
- pH papers are portable so you can take it with you.
- This is a very cheap method of pH determination.
- pH strips and paper provide more precise as compared to liquid indicators.
- The color of paper changes as per the pH.
The disadvantages of a pH paper:
- It does not determine the exact pH of the solution, as compared pH meter
- Only colorless solutions can give better results.
- Doubt on reproducibility.
- The possibility of solution contamination is high because the pH paper is in contact with the air and it is non-washable.
