pH formula?

[Saleha_Mian_3E]

What is the pH formula? and do we need to know how it was derived?

[Sierra Cheslick 2B]

The pH formula is -log[H+]. I believe we would need to know how to derive it.

I don't think we need to know how to derive it since pH is just an invented representation of proton concentration. For acid it's (-log[H+]), for base it's 14 - (-log[OH-])

[Jonathan Cheng 3C]

pH = - log[H+] while pOH is either 14 - pH or -log[OH-]. We do not need to know how these formulas were derived.

[Henri_de_Guzman_3L]

We don't need to know how they're derived although reading through the textbook I feel it is helpful in understanding how they work.

[Krista Mercado 1B]

The pH formula is pH = -log[H+]. I don't think we need to know how it is derived.

[Lisa Werner 2F]

I think you also need to know that pH + pOH = 14.

@305127455 wait shouldnt pOH be 14-(-log[H+]) ?
