A Definition of pH

WebJan 23, 2016 · pH = − log [ H X +] = − log [ H X 3 O X +] You can obtain the concentration of H + ions by substituting the value of pH in the following formula, [ H X 3 O X +] = 10 − p H. … WebHNO3 is a strong acid, so every single HNO3 molecule breaks apart into an H (+1) ion and an NO3 (-1) ion. This means 0.1 mol/L of HNO3 yields 0.1 mol/L of H (+1) ions. So the pH is … WebpH= −log[H3O+] pH = − log [ H 3 O +] Rearranging this equation to isolate the hydronium ion molarity yields the equivalent expression: [H3O+] = 10−pH [ H 3 O +] = 10 − pH Likewise, the hydroxide ion molarity may be expressed as a p-function, or pOH : pOH= −log[OH−] pOH = − log [ OH −] or [OH−] = 10−pOH [ OH −] = 10 − pOH helsinki missio itsemyötätunto
