HEATS OF DILUTION AND RELATIVE APPARENT MOLAL ENTHALPIES OF AQUEOUS SODIUM PERCHLORATE AND PERCHLORIC ACID¹

Asparagine Deamidation Dependence on Buffer Type, pH, and Temperature

“…From Eq. 11, the E a can be determined by subtracting the H w 25 and adding the H bf 24. After correction with H w (13.6 kcal/mol) and H bf , the E a for Fc deamidation at pH 7.4 is 11.8 kcal/mol in 20 mM Tris/Tris–HCl and 11.8 kcal/mol in 20 mM sodium phosphate; at pH 5.3, the E a is 8.9 kcal/mol in 20 mM sodium acetate and 13.2 kcal/mol in 20 mM histidine chloride.…”

A revised Pitzer model for low-temperature soluble salt assemblages at the Phoenix site, Mars

“…Experimentally derived values for / L fromVanderzee and Swanson (1963) (NaClO 4 , h),Gier and Vanderzee (1974) (Ca(ClO 4 ) 2 , +), andJongenburger and Wood (1965) (Mg(ClO 4 ) 2 , x). Modeled values using Eq.…”

Enthalpies of dilution and related thermodynamic properties of aqueous hydrobromic acid

“…The pattern of dilution measurements followed that of other studies in this laboratory (75,77,19). In summary, a series of interconnected dilutions were made to delineate the low molality range, and individual dilutions from higher molalities were referred to the low molality region after it had been fitted to the Debye-HUckel smoothing and extrapolation function used for previous studies (15,17). The solutions used to delineate the range of molalities below 1m were all referred to the same NaOH solution to eliminate possible distortion from analytical errors.…”
