Determination of sodium in water by titration
Webf. Sodium Thiosulfate working solution (0.018 M: reagent grade): Bring 100 mL of the sodium thiosulfate stock solution to 1000 mL with distilled water in a 1 liter volumetric flask. This solution is stored in a refrigerator and used for titrations. If a ready-made 0.1 N solution was used for the stock, a working solution of 0.01 N will be fine. g. Web5. Allow the sodium carbonate to cool in a desiccator. 6. Weigh by difference (to the nearest 0.1 mg) three or four 0.20-0.25 gram portions of the dry material into clean 500 mL Erlenmeyer flasks. Titration of Standard Sodium Carbonate: perform 3-4 trials. 7. Add about 100 mL of distilled water to each sample of pure sodium carbonate in the 500

As titration is an absolute method, the linearity can usually be obtained directly. For this, at least five different concentrations are titrated and a linear regression of the sample size versus the consumed titration volume is established. To evaluate the linearity, the coefficient of determination (R 2) is used. The recommendation is ...
WebTitration is used to determine the concentration of an unknown solution n by adding another solution of known concentration. The concentration of sodium Hydroxide was to be 0.39M(titrant). The volume of The base used to neutralize the acid is used to calculate the molarity. The molarity of the titrant used is equal to the unknown solution.
