Copper (II) ion

21
Q

Test and test result for carbonate anion

A

Add dilute acid. Effervescence, carbon dioxide produced.

22
Q

Test and test result for chloride anion

A

Acidity with dilute nitric acid, then add aqueous silver nitrate. White ppt forms.

23
Q

Test and test result for bromide anion

A

Acidify with dilute nitric acid, then add aqueous silver nitrate. Cream ppt forms.

24
Q

Test and test result for iodide anion

A

Acidify with dilute nitric acid, then add aqueous silver nitrate. Yellow ppt forms

25
Q

Test and test result for nitrate

A

Add aqueous sodium hydroxide, then aluminium foil; warm carefully. Ammonia is produced.
