More negative ion stuff sorry :(
We are now going to test for Sulphates with Hydrochloric acid and Barium Chloride
- Sulphate ions produce a white precipitate
- To test for Sulphate ions add dilute HCL followed by Barium Chloride
- If the solutions turns white then it means the original compounds was a sulphate
Tests for Halides (Cl-, Br-, I- ) with Nitric Acid and Silver Nitrate
Soo basically you start off with one of them halides and add dilute nitric acid and then Silver nitrate :)
If you start with Cl- you get a WHITE precipitate of SILVER CHLORIDE
If you start with Br- you get a CREAM precipitate of SILVER BROMIDE
And finally if you start with I- you get a YELLOW precipitate of SILVER IODIDE
Well thats all the tests for Positive and Negative Ions, learn it god says we need to, and i'll be doing the C3 test with you Good Luck !! :D
