lithmus
The indicator is bromothymol blue.
A pH indicator is used only to measure the pH of the solution.
Universal indicator...
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
Ph indicator
The indicator is bromothymol blue.
universal indicator
A pH indicator is used only to measure the pH of the solution.
pH range of indicator should be in the rapid pH gradient.
Universal indicator...
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
indicator
A pH indicator paper can be used to tell if a solution is acidic or basic and the rough pH range can be known
An example of an indicator would be Phenol Red, or Universal Indicator. Depending on the pH range of the indicator and the pH range of the substrates you would use the appropriate indicator.
Litmus paper goes red or blue in acids or universal indicator may measure some level of pH
Ph indicator
It is a chemical solution used for knowing the pH of a substance. Eg. You mix a drop of Universal indicator solution with approx 5 mL of the substance whose pH you want to know.You can compare the color with a standard pH chart and know the pH.
