WebA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. This is due to the changing value of water's self-ionization constant, … 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
Web[H3O+] = [OH -] = 1.0 x 10 -7 pH = -log [H 3 O +] pOH = -log [OH -] pH + pOH = 14 [H 3 O +] = 10 -pH 1.
