The effect of solute concentration on fluidity and structure in aqueous solutions of electrolytes—V. Strong acids and alkali-metal hydroxides
Abstract An examination has been made of the effect of concentration on the temperature dependence of fluidity in aqueous solutions of the strong acids HCl, HBr, HNO 3 , HClO 3 , H 2 SO 4 and H 3 PO 4 , and the alkali-metal hydroxides LiOH, NaOH and KOH. The results suggest that, because of ion association and complex hydration effects in the other systems, only HCl and KOH are capable of giving the least equivocal information about the behaviour of H + and OH − in fluid motion. It is also concluded that both H + and OH − are positively hydrated structure-brea entities, and that despite their special properties their effect on fluidity is not materially different from other positively hydrated structure-break ions.
