Heats Of Dilution

Heats of solution of MnSO4(c) have been measured and combined with heats of dilution to yield ΔH0 = −15.3 kcal/mole for the standard heat of solution. This value leads to ΔHf0 = −52.9 kcal/mole for Mn2+(aq). Calculations with data from the literature give ΔGf0 = −55.1 kcal/mole for Mn2+(aq). Combination of this value with our ΔHf0 gives [Formula: see text] for Mn2+(aq). Our ΔHf0 value for Mn2+(aq) is compared with other values derived from calculations based on data taken from the literature.

Bonding Effect

Densities, ultrasonic velocities and viscosities of L- Valine and L- Phenylalanine in aqueous sodium bromide (0.00, 0.025 and 0.05) m solutions have been determined experimentally at 308 and 313 K. The results obtained from density ultrasonic velocity and viscosity measurement have been used to calculate the apparent molal volume, фv, apparent molal, adiabatic compressibility ф Ks, partial molal volume ф0v at infinite dilution, partial molal adiabatic compressibility ф0Ks at infinite dilution, transfer volume ∆ф(tr), experimental slopes Sv and SKs,Falkenhagen coefficient A and  Jones-Dole B coefficient. The results are discussed in terms of the dehydration effect of the sodium bromide upon the amino acids and weak solute- solute and strong solute- solvent interactions. The properties of these amino acids in water and water + sodium bromide solution systems are discussed in terms of the charge, size and hydrogen bonding effect.
