testing for anions Flashcards
1
Q
Carbonate (CO 3 2 – )
A
Add dilute acid. resulting in = Effervescence and carbon dioxide will be produced.
test for carbon dioxide using limewater
2
Q
Chloride (Cl – )
A
Acidify with dilute nitric acid, then add aqueous silver nitrate. the result is = White ppt.
3
Q
Bromide (Br – )
A
Acidify with dilute nitric acid, then add aqueous silver nitrate. the result is = cream ppt.
4
Q
Nitrate (NO 3 – )
A
Add aqueous sodium hydroxide then aluminium foil. the result is = Ammonia gas produced (turns damp red litmus paper blue)
5
Q
