Stanovení pH moči
From WikiLectures
The pH indication zone contains a mixture of selected acid-base indicators. Most use two acid-base indicators - methyl red and bromothymol blue, or phenolphthalein . This ensures that the pH is read in the range 5-9 by changing the color from orange (acidic pH) to green to blue (alkaline pH). The reading is possible with an accuracy of 0.5.
