WebKw, the equilbrium constant for the autoionization of water (H2O = H^+ + OH^-is: Kw = [H^+] [OH^-] = 1.0E-14 at 25 deg C In a neutral solution, [H^+] = [OH^-] =1.0E-7 Thus, in a neutral solution, pH = -log [H^+] = 7.00 and pOH = [OH^-] = 7.00. In an acid solution, pH will be lower than 7.00 and pOH will be higher than 7.00.

WebExpert's answer The H3O+ ion is considered to be the same as the H+ ion as it is the H+ ion joined to a water molecule. The proton cannot exist in aqueous solution, due to its positive charge it is attracted to the electrons on water molecules and the symbol H3O+ is used to represent this transfer [H^+] [OH^-]=10^ {-14}\\ [H +][OH −] = 10−14 WebIn the autoionization of water, a proton is transferred from one water molecule to another to produce a hydronium ion (H₃O⁺) and a hydroxide ion (OH⁻). The equilibrium expression for this reaction is Kw = [H₃O⁺] [OH⁻], where Kw is the autoionization constant for water. At 25°C, the value of Kw is 1.0 x 10⁻¹⁴. noth the plaguebringer wow
