GB/T 6682-2008 analytical laboratory use specifications and test methods
Method 3 silver
3.1 Principle
Sample solution was neutralized with potassium chromate as indicator, titrate with standard silver nitrate titration, determination of chlorine ions.
3.2 Reagents
3.2.1 Reagents Specifications
Unless otherwise indicated in the analysis using only recognized as analytical reagents and GB/T 6682-2008 specified tertiary water.
3.2.2 sodium chloride standard solution
Weigh 5.844g was burning 600 ℃ to constant weight of sodium chloride reference reagents, weighing accuracy of 0.0001g, dissolved in water, transferred to a
1000mL volumetric flask, add water to the mark.
The concentration of sodium chloride standard solution in accordance with the formula (1).
c (NaCl) = m58.44 × V
(1)
Where.
c (NaCl) --- the concentration of sodium chloride standard solution, unit mole per liter (mol/L);
m --- said to take quality of sodium chloride, in grams (g);
58.44 --- sodium chloride molar mass in grams per mole (g/mol);
Preparation of the V --- volume of the solution, in liters (L).
3.2.3 standard silver nitrate titration solution
Preparation. Weigh 85g of silver nitrate dissolved in 5L of water, mix well stored in a brown bottle spare (if cloudiness should be filtered).
Calibration. lessons 20.00mL sodium chloride standard solution (3.2.2), placed in 150mL beaker, as measured in step 3.4.2 will be dropping
Fixed, while doing the blank test.
