The solid phases of aqion are listed here in two tables (together with the solubility product in form of pK sp = - log 10 K sp):. $\ce{KHCO3}$ does not readily decompose into $\ce{CO2}$ when dissolved in water. The self-ionization of water (also autoionization of water, and autodissociation of water) is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H 2 O, deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, OH −.The hydrogen nucleus, H +, immediately protonates another water molecule to form hydronium, H 3 O +. bicarbonate ion could be forced to dissociate if it was in a basic [H 3 O +] = [OH-] = 1.0 x 10-7 M (at 25C) When we add a strong acid to water, the concentration of the H 3 O .
