Question

What is the relationship between [H+] and pH?

Answer 1

pH = -log[H+]

or, putting it the other way round,

[H+] = 10^-pH

Answer 2

pH is actually the measure of conc. of H+ ions in a solution ... its equal to the negetive logirithm of the cdonc of H+ ions in sol

a sol having less pH has more H+ ions then a solution with more pH

pH=-log(base10)[H+]

Answer 3

(pH) is the negative of the logarithm to the base ten of the hydrogen ion concentration(H+) of a substance(molecule).

pH=-log[H+]

Answer 4

pH = - log [H+]= log1/[H+]

log is decimal log
