The flasks were closed by ground glass stoppers and stored at the required temperature in a thermostat for 45 hours, with intensive stirring every several hours. After this, 5 mL samples of the saturated solution were taken by pipette, diluted to 25 mL with water and titrated against 0.1 N sodium hydroxide solutions by using phenolphthalein indicator.
