The pH is a measure of the activity of the ion H+ (the negative logarithm in base 10); the scale is logarithmic.
The acidity range is a part of the pH scale.
You use Universal Indicator solution.
It depends on what indicator you are using. Yellow with the bromothymol blue indicator is acidic, yellow with the methyl orange indicator is basic, yellow with the phenol red indicator is acidic and yellow with the universal indicator is acidic.
Each indicator has a specific change of color when the pH is changed.
The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
its linked because universal scale is specificly diifferent in colour and scientist use it as acid tester also alkali.the ph scale is for testing if a indicator is a indicator
it indicate the acid and base of the scale
The acidity range is a part of the pH scale.
pH Scale
No, it is an alkali according to the pH scale or pH indicator.
Indicators are substances sensitive to different ranges of pH.
A unique and correct pH indicator for all the values of the pH scale don't exist; see the link below.
You use Universal Indicator solution.
red. on the PH scale it is 1.
Neutral is a word that describes a chemical which turns a universal indicator green. This chemical has a pH equal to 7.0 on the pH scale.
It depends on the sensitivity of the indicator you are using. There should be a guide with the indicator you are using. Litmus paper, which is the most common form of pH indicator, will change fairly constant across the pH scale, but a neutral (pH 7+/- 0.5 about) solution will normally not cause a change.
A pH indicator will test a substance to determine the alkali or acidity, with 7 being neutral on the pH scale.
