Dilute Aqueous Solution

Several complexes have been prepared with selected divalent transition metal cations and either p-tosyl lysine or p-tosyl glutamic acid; both acids were the L isomer. These complexes were synthesized in dilute aqueous solution and have been studied polarographically. Eight previously unreported compounds were prepared and studied, and their dissociation constants and coordination numbers are reported in this paper. The calculated Free Energies of Formation are also reported.

The Schiff base, N-n-butylsalicylideneimine, extracts more than 99.8% beryllium into toluene from dilute aqueous solution. The distribution of beryllium has been studied in the pH range 5-13 and is discussed in terms of the several complex equilibria in aqueous solution. The stability constants of the complexes formed between beryllium and the Schiff base are log β1 11.1 and log β2 20.4, and the distribution coefficient of the bis complex is 550. Over most of the pH range, hydrolysis of the Be2+ ion competes with complex formation and provides a means of measuring the hydrolysis constants. They are for the reactions: Be(H2O)42+ ↔ 2H+ + Be(H2O)2(OH)2, log*β2 - 13.65; Be(H2O)42+ ↔ 3H+ + Be(H2O)(OH)3-, log*β3 -24.11.
