Final answer:
Iron(III) nitrate reacting with sodium phosphate is an example of a precipitation reaction where an insoluble substance, likely iron(III) phosphate, is formed.
Step-by-step explanation:
When iron(III) nitrate reacts with sodium phosphate, the resulting reaction is a type of ion exchange reaction known as a precipitation reaction. This is because the products of the reaction include an insoluble solid known as a precipitate. No electron transfer occurs, so it is not a redox reaction, and it does not involve acid-base neutralization, so it is not an acid-base reaction. It is also not a complexation reaction as there is no formation of a complex ion.
In the case of iron(III) nitrate reacting with sodium phosphate, the insoluble product formed would likely be iron(III) phosphate, based on solubility rules indicating that most phosphates are insoluble except those of the alkali metals and ammonium.
