Will a precipitate form when an aqueous solution of (NH4)4CO3 is mixed with Fe(NO3)3
1 answer
Probably so but it probably will not be Fe2(CO3)3. Most likely the ppt will be Fe(OH)3. However, one must remember that high concns of NH4^+ [you're adding (NH4)2CO3] reduces the OH^- in solution and hydroxide ppts sometimes don't appear.
