What is the equation for pH
pH = -Log10[H+]
What is the equation for [H+]
[H+] = 10^- pH
What is the ionic product of water equation
Kw = [H+] [OH-]
When calculating the pH of a strong acid what do you use
pH = -Log10[H+]
What equation do you use when calculating the pH of a strong base
Rearrange Kw = [H+] [OH-] to get [OH-] the use pH = -Log10pH
What equation do you use when calculating the pH of a weak acid
Ka = [H+]^2 / [HA] and rearrange to get [H+]
What equation do you use when calculating the pH of a buffer use
Ka = [H+] [A-] / [HA] and rearrange to get [H+]
