It depends on the reagent used, but most of the time the more acidic the substance is, the brighter yellow it shows up on the scale when a sample is tested for pH, while strong bases are usually deep blue. Greens are usually in the 7.0 range, or neutral. Your pH testing substance should come with a color scale, and you just match up the color of your testing strip after dipping it or touching it to the test substance with the color on the scale.

What does red mean on the pH scale?
The meaning is a basic solution.
What number is highest on the pH scale?
The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
What scale measures the concentration of hydrogen ions?
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
What is the midpoint of the pH scale?
The midpoint of the pH scale is 7.
If an pH scale is up to 7 or 8 what does it mean?
If the number on the Ph scale is 7 then that means its neutral, neither an acid nor an alkali. If its eight, it is most likely an acid.
What colour is acid on a PH scale?
The Ph scale does not have colours.
What does the number seven mean on a pH scale?
it is neutral. Water is a 7 on the pH scale
What does phtwo mean in sciene?
The phtwo is another name for the ph scale.
What Does high pH mean on a pH scale?
A pH over 7 is basic.
What base mean in science on the pH scale?
A soluble base is an alkali, so above 7 on the pH scale.
What does it mean to be a strong or weak acid or base?
a strong acid is lower on the pH scale a strong base is higher on the pH scale
Is 6 a natural number?
The number 6 is not a natural number on the pH scale if that is what you mean. In fact the number 7 is a natural and neutral number on the pH scale ( on the pH scale number 7 is a green colour.)
What do mean pH scale?
The pH scale is from 0 to 14; pH is a measure of acidity/alkalinity of a solution.pH= 7 is neutral; under 7 is acidic, over 7 is alkaline.
Where are fluids with an acid pH found?
if you mean on the pH scale they are found from numbers 0-7
What does red mean on the pH scale?
The meaning is a basic solution.
What scale is used to determine pH?
the pH scale
Can you tell if something is acidic on the pH scale?
The pH scale ranges from acids to alkali's. The strongest acid is red then it gets lighter, (orange, pale, yellow) then it goes to green (neutral) and alkali's are more dark greenish purple colours. Hope this helped. :)
