What number on the pH scale is the most acidic?
A pH of 0 is the most acidic on the pH scale.
What is neutral on the PH scale?
The pH scale runs from 1 - 14. A pH neutral substance like rainwater has a pH of 7. Lower numbers are acidic substances, higher numbers are alkaline. Note that impurities in the air can cause rain to become acid, sometimes enough so to cause damage to trees and buildings.
Is the pH scale linear?
NO!!! The 'p' in pH is short for 'the negative logarithm to base 10. The 'H' is for the hydrogen ion concentration. pH = -log(10)[H+] Mathemtically inverting [H^+] = 10^(-pH) So pH = 1 is equivalenrt to 10^-1 = 0.1 pH = 2 is equivalent to 10^-2 = 0.01 pH = 3 is equivlaanrt to 10^-3 = 0.001 : pH = 7 is equivalent to 10^-7 = 0.0000001 : pH = 14 is equivapanet to 10^(-14) = 0.00000000000001 So hopefully you can see that is is decreasing in powers of '10'. on an exponential scale. On a graph this will produce a curve, not a straight line.
Are there decimals in the pH scale?
Yes. For example the pH of blood is maintained between 7.35 to 7.45.
