Electrolytic Studies Of Glycine And DL-α Alanine In 1:1 Electrolytic Aqueous Solutions Of Halide Salts Of Alkali Metals At 308.15 K

Man Singh, Maneesha Pandey

Electromotive force (EMF) of concentration cell with transference number (t+) has been obtained for glycine and DL-α alanine in 1:1 electrolyte (NaCl, KCl, RbCl and NaI, KI, RbI) solutions at 308.15 K. The cell electrodes work of Ag-AgCl type have been prepared from Ag2O paste in water and based on the liquid-liquid junction potential. The activity coefficient data are derived from the measured EMF values and are discussed in terms of pairewise interactions to interpret the amino acid interactions with salts in aqueous solutions. The effect of the -CH3 of the alanine is noted to weaken the activity of the acids due the hydrophobic interactions and the iodide ion I- has depicted its induced potential impact on the interactions.
