✦ Synopsis

Transport number experiments on mixtures of hydrochloric and maleic acids showed that the mobility of the maleate ion increases, whereas that of the H+ and Cl-ions decreases, with increase in maleic acid concentration up to 0.12 M. Conductance measurements indicated an initial rise in the specific conductance of HCl with increase in maleic acid concentration.

These results are interpreted on the basis of an increase in the ice-like structure of liquid water through the presence of maleic acid.

R&nn&Mesures

de nombres de transport sur des melanges dissous d'acides chlorhydrique et malelque: quand la concentration d'acide maleique croit jusqu'a 0,12 M, la mobilitt des ions maleate augmente tandis que celles de H+ et Cl-diminuent. La conductivite s'accroit, II partir de celle de HCI seul, lorsqu'on accrolt la teneur en acide male'ique, ce qui s'interprete par un renforcement de la structure semi-glace de l'eau liquide, en presence d'acide malelque.
