3
New cards

Bromide (Br-) aq

gives cream/off-white ppt with Ag+ (aq) - this ppt is partially soluble in NH3 (aq)

4
New cards

Iodide (I-) aq

5
New cards

Nitrate (NO3-) aq

NH3 liberated on heating with OH- (aq) and Al foil

6
New cards

Nitrite (NO2-) aq

NH3 liberated on heating with OH- (aq) and Al foil
decolourises acidified aqueous KMnO4
