Jul 30, 2019· Sodium Chloride AR Procedure: Weigh accurately about 10 g of sample (W) and dissolve in 100 ml of water. Add 100 ml of ethanol (95%) and extract the solution with three quantities, each of 50 ml of n-pentane, adding sodium chloride, if necessary, to promote separation of the two layers.
Sodium chloride solution— Dissolve 2.5 g of Sodium Chloride in 50 mL of water. Procedure— To 1.5 mL of Standard sulfate solution A add 1 mL of a barium chloride solution (1 in 4), shake, and allow to stand for 1 minute. To 2.5 mL of the resulting suspension, add 15 mL of the Sodium chloride solution and 0.5 mL of 5 N acetic acid, and mix (Test solution).
Assay test: Dissolve 1.0 g of ammonium chloride in 20 ml of distilled water. Add a mixture of 5 ml formaldehyde solution which is previously neutralize with 0.1 M NaOH (why?) and 20 ml distilled water. Leave it for 2 minutes, and then titrate slowly with 1M sodium …
