What is the definition of pH?

IT IS THE NEGATIVE log OF H+ ION CONCENTRATION.

Oh, no need to shout. So, pH = - log [H+]? Can you rearrange that to isolate [H+], or perhaps more accurately, rearrange 0 > -log [H+]?

Ph=-log[H]Λ+

Sorry it doesnt work that way here.
Anyway, try some calculations of pH when [H⁺]= 0.1, 0.5, 1, 2, 3
