Accuracy And Composition Of PH Wide Test Strips
- Aug 07, 2018 -

The indicator components on a wide range of pH test strips: methyl red, bromocresol green, and thymol blue, when exposed to an acid-base solution, show different colors in different pH ranges.
Concentration: methyl red: 2g/L
Bromocresol green: 1g/L
Thymol blue: 1g/L
The accuracy of the wide PH test paper, precision PH test paper and acidity meter are different. The pH meter (acidity meter) has the highest accuracy and the wide pH test paper has the lowest accuracy. The accuracy of the three is as follows: precision pH test paper Accurate to 0.1; wide pH test paper can be accurate to 1; pH meter accurate to 0.01.
