3 PRINCIPLE OF THE METHOD

Soluble salt is stannous sulfate, stannous ion but easily hydrolyzed stannous hydroxide [Sn (OH) 2Ksp = 1.4 × 10-28], because The dissolution with hydrochloric acid, filtered, washed and dried to obtain the content of hydrochloric acid insolubles.

4 Safety Tips

Reagents used in this test method is corrosive, be careful when operating! As water immediately splashed on the skin or eyes Flushing, severe cases should be treated immediately.

5 General Provisions

This standard reagents and water, did not indicate when the other requirements, refer to analytically pure reagents and GB/T 6682-2008 stipulated three Grade water. Used in the test preparation and products, did not indicate when the other requirements, according to GB/T 603 or HG/T 3696.3 of preparation.

6 Reagents

6.1 hydrochloric acid; 6.2 hydrochloric acid solution. 2 + 1; 6.3 Silver nitrate solution. 10g/L.

7 instruments and equipment

7.1 sintered glass crucible. sand core pore size of 5μm ~ 15μm. Glass sand crucible should always use 1 + 1 hydrochloric acid boiling 15min ~ 30min, and then tap water rinse, washed three times with three water, After then dip in boiling water three 15min, hot filtration at 105 ℃ ± 2 ℃ under dried to constant weight. ......
