Abstract

The deprotonation constant of glycine in 10%, 20% and 30% dioxane in dioxane-water system at 298.15 K was determined using the cell:

H2(Pt) | Glycine, HCl, X% Dioxane, Hg2Cl2 | Hg …(C-1)

m1 m2

and e.mf. of the cell was given by 

E = E0 - (2.303RT/F) (log mH+ mCl_ + log ?H+ ?Cl_) …(1)

where log ?H+ ?Cl_ = - (2A’√μ/(1+√μ) ) + ?1μ (Modified Davies Equation) …(2) 

which has been given by B Prasad in our laboratory called modified Davies equation for calculating activity coefficient in the system and hence deprotonation constant of glycine can be calculated by calculating mH+ given by the formula:

log mH+ = (E0 - E)/K - log mCl_ + (2A’ √μ/(1+ √μ)) - ?1μ …(3)

Therefore Free energy transfer can be calculated for 10, 20 and 30% dioxane in dioxane-water system during determination of deprotonation constant of glycine at 298.15 K.
