Abstract (English):
Under an argon atmosphere, and air the titration curves of solution Sn(II) 0,1 mol / l by standard solution of KOH were obtained. The «memory effect» of solutions is the existence in the system slowly forming compounds. By comparing the results of potentiometric titration revealed the influence of air on the formation of tin compounds. The constants of equilibria in the Sn(II)-H 2O-OH - with the «memory effect» of solutions was achieved.
