Question

The compound iron(III) nitrate is a strong electrolyte. Write the transformation that occurs when solid iron(III) nitrate dissolves in water. Be sure to specify states such as (aq) or (s).

Answer 1

Answer:

Fe(NO₃)₃ (s) →   Fe³⁺ (aq)  +  3 NO₃⁻ (aq)

Explanation:

The iron (III) nitrate is a salt, that can be 100 % dissociated in water.

Fe(NO₃)₃ (s) ⇒ Fe³⁺ (aq)  +  3 NO₃⁻ (aq)

It is not considered 100% neutral, because Fe³⁺ can release protons to water, when it is hidrated. It works similar as the Al ³⁺.

NO₃⁻ (aq)  + H₂O (l) ←  OH⁻(aq)  +  HNO₃(aq)

This reaction can not occur. Nitrate is a weak base, derivated from a strong acid, so it can't make hydrolysis.

Salt can be a little acid, because Fe³⁺ react to water to give protons, and a determined complex

Fe³⁺ (aq)  +  H₂O(l)  ⇄  Fe(OH)²⁺ (aq)  +  H⁺(aq)
