Question

what is the formula for ammonium bromide? what is the formula for ammonium sulfite? what is the formula for ammonium iodide?

Explanation:

Ammonium has a +1 charge ($NH_4^+$). Bromide is $Br^-$, sulfite is $SO_3^{2 -}$, and iodide is $I^-$. To form a neutral - compound, the charges must balance.

Answer:

1. Ammonium bromide: $NH_4Br$
2. Ammonium sulfite: $(NH_4)_2SO_3$
3. Ammonium iodide: $NH_4I$
