Effect of ionic strength on the formal potential of the glass electrode in various saline media
Brandariz, Isabel; Vilariño, Teresa; Alonso Suárez, Pablo A.; Herrero, Roberto; Fiol López, Sarah; Sastre de Vicente, Manuel (Elsevier, 1998-08)We examined the variation with ionic strength (I, adjusted with KCl, KNO3, KBr, NaCl or NaClO4) of the formal potential (Econst) for glass electrodes exhibiting a Nernstian response (i.e. Ecell=Econst−s log [H+]). For this ... -
Equilibrium constants of triethanolamine in major seawater salts
Brandariz, Isabel; Castro, P.; Montes, María; Penedo Blanco, Francisco José; Sastre de Vicente, Manuel (Elsevier, 2006-12)Acid–base equilibrium constants of triethanolamine (TEA) have been determined by potentiometric titrations with a glass electrode, at 25 °C. Ionic strength was kept constant with only one electrolyte (using one of these ... -
The salting coefficient and size of alkylamines in saline media at different temperatures: estimation from Pitzer equations and the mean spherical approximation
Taboada Pan, Carlos.; Brandariz, Isabel; Barriada, José Luis; Vilariño, Teresa; Sastre de Vicente, Manuel (Elsevier, 2001-04)The renewed theoretical interest in the proton transfer associated to the amino group together with the scarcity of acid-base studies of amines in moderate to concentrated saline media focussed our attention on the study ...
