Net ionic equations using NH3 ammonia
« on: October 27, 2005, 03:59:50 AM »
I understand that NH3 is a weak base that reacts with water to produce hydroxide ions.

During a lab i reacted, NH3 with Mg(NO3)2, Co(NO3)2,  Ba(NO3)2, and NaNO3-  (All were Aquaous solutions)

I formed precipitates for all reactions except for NaNO3-.

I am not sure how to write the net ionic equations for the 3 observed reactions.

I am unaware of the solubility rules for NH3. if someone can help start me out , I'd appreciate it.

Hello,
 Hint 1:

NH3 + H2O = NH4(+1) + OH(-1)

Mg(NO3)2 + H2O = Mg(+2) +2 NO3(-1)

Hint 2:

Look at the solubility constants for the products.

Hope this helps.

all group I hydroxides are water-soluble.
