Question

(1) -        Write the net ionic and formula unit equations for the following:

                (i)            iron(III) acetate and sodium carbonate

                ii)             magnesium perchlorate and potassium hydroxide

(2) -        Write the net ionic and formula unit equation for the reaction between mercury(II) nitrate and         potassium iodide (look up the solubility rules for iodide!).

                i)              The supernatant liquid was collected from the above precipitation reaction When                                                mercury(II) nitrate was added to the supernatant solution, no further precipitation                                               occurred. When     potassium iodide was added to the supernatant solution, a precipitate                                     formed. Which reagent is the limiting reagent?

                ii)             If 5.00 ml of 0.15 M mercury(II) nitrate was reacted with 8.00 ml of 0.18                                                              M potassium iodide, what is the theoretical yield for the reaction?

Answer 1

Hello, i am sorry to say that as per Chegg guidelines experts can answer only one full question that too first question only. I request you to please post remaining question as separate one since my allotted time could not permit me to answer more than one question also. Thank you in advance for your continued support to us.

Net ionic equation involves species which gives only a new molecule or a precipitate.

^ symbol superscript indicates that the immediate preceding terms should be placed at superscript on those species except bracket terms like (s), (aq). Species present as (aq) in both sides should be omitted in net ionic equation.

(1) net ionic and formula unit equations

(i) iron(III) acetate and sodium carbonate

formula unit equation: 2 Fe(CH3COO)3 (aq) + 3 Na2CO3 (aq) => Fe2(CO3)3 (s) + 6 CH3COONa (aq)

net ionic: 2 Fe^3+(aq) + 3 CO3^2-(aq) => Fe2(CO3)3 (s)

(ii) magnesium perchlorate and potassium hydroxide

formula unit equation: Mg(ClO4)2(aq) + 2 KOH(aq) => Mg(OH)2(s) + 2 KClO4(aq)

net ionic: Mg^2+(aq) + 2OH^-(aq) => Mg(OH)2(s)

Hope this helped you!
