Question

Please complete the following reactions and show the total ionic and net ionic forms of the equation.

NOTE! You need to make sure the original equation is balanced before proceeding.
3. Chromium Nitrate + Iron Il Sulfate →
4. Hydrochloric Acid + Sodium Hydroxide →

Answer 1

3.

Chromium Nitrate: Cr(NO3)3

Iron II Sulfate: FeSO4

2Cr(NO3)3 (aq) + 3FeSO4 (aq) --> 3Fe(NO3)2 (aq) + Cr2(SO4)3 (s)

Net ionic form: 2Cr 3+ (aq) + 3SO4 1- (aq) --> Cr2(SO4)3 (s)

4.

This problem is interesting because it utilizes bronsted lowry acids and bases. The first thing to note is both HCl and NaOH will dissociate in water prior to the reaction.

HCl + H2O --> Cl 1- + H3O 1+

NaOH + H2O --> Na 1+ + OH 1-

When you have a reaction between a strong acid (HCl) and a strong base (NaOH), the net ionic equation that it follows will be:

H3O 1+ (aq) + OH 1- (aq) --> 2H2O (l).
