Resumo

LOSHALI, RENU  e  DATT KANDPAL, NARAIN. VISCOMETRIC BEHAVIOR OF CONCENTRTED PERCHLORIC ACID. J. Chil. Chem. Soc. [online]. 2017, vol.62, n.1, pp.3386-3388. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072017000100016.

Viscosity q and density p of aqueous concentrated perchloric acid 1.0 moldm-3 to 9.0 moldm-3 were measured at 297.65K. The viscosity data were used to calculate the value of A and B-coefficient of Jones-Dole equation. The value of B-coefficient is positive which suggests the strong ion-solvent interaction in aqueous perchloric acid. The three concentration regions of perchloric acid having value of B-coefficient (measure of ion-solvent interaction or structure making capacity) in the order 1.0 to 4.0 moldm-3 < 4.0 to 6.0 moldm-3 < 6.0 to 9.0 moldm-3 has been proposed.

Palavras-chave : Solution perchloric acid; viscosity equations; interaction parameters.
