WebpH = - log [H 3 O +] Similarly, pOH is the negative of the logarithm of the OH - ion concentration. pOH = - log [OH -] pH + pOH = 14 The equation above can be used to convert from pH to pOH, or vice versa, for any aqueous solution at 25C, regardless of how much acid or base has been added to the solution. WebAnd so, at this temperature, acidic solutions are those with hydronium ion molarities greater than 1.0 × × 10 −7 M and hydroxide ion molarities less than 1.0 × × 10 −7 M (corresponding to pH values less than 7.00 and pOH values greater than 7.00). Basic solutions are those with hydronium ion molarities less than 1.0 × × 10 −7 M and hydroxide ion molarities …
