Can anybody tell me a method about 0,1 M Sodium nitrite standardisation?
We use a method, but it is not properly work.
Our method:
Add 0,15 g sulfanilic acid and 2 ml 2M NaOH +2 ml H2O. Add 30 ml 20 % HCL solution. After this we titrate with 0,1 M sodium nitrite.
How long can we store 0,1 M sodium nitrite?
