Write balanced net ionic equAtions.
D) zinc chloride and excess ammonia
E) cupric phosphate and lots of ammonia
A) ammonia and excess zinc sulfate
What do you not understand? Can you write the balanced molecular equation?
I don't know what they form...
D) ZnCl2+ NH3--->
E) Cu3(PO4)2 +2NH4OH--->
A) NH3+ ZnSO4-->
I don't understand what it means by excess... How do I figure out what they form.
ZnCl2 and excess NH3 forms the ammine complex Zn(NH3)4Cl2
Cu ion reacts with NH4OH to form Cu(NH3)4^2+ complex ion.
NH3 and ZnSO4 does the same as ZnCl2 except it's Zn(NH3)4SO4 and not Zn(NH3)Cl2
