1. a) Predict whether a reaction will occur when FeSO4 (aq) and Pb(NO3)2 (aq) solutions are mixed. (What is the driving force?) And if yes, determine the spectator ions and the net ionic equation for the reaction.

b) Predict whether a reaction will occur when HClO (aq) and Sr(OH)2 (aq) solutions are mixed. And if yes, determine the spectator ions and the net ionic equation for the reaction. (HClO is hypchlorous acid, a weak acid)

Expert Solution

1. a) Iron(II) sulfate react with lead(II) nitrate to produce iron(II) nitrate and lead(II) sulfate. This reaction takes place at a temperature near 10°C in a nitrogen atmosphere.

The balanced equation: Pb(NO₃)₂(aq) + FeSO₄(aq) → PbSO₄(s) + Fe(NO₃)₂(aq)

complete ionic equation: Pb²⁺(aq) + 2NO₃^-(aq) + Fe²⁺(aq) + SO₄^2-(aq) PbSO₄(s) + Fe²⁺(aq) + 2NO₃^-(aq)

spectator ions: NO₃^- and Fe²⁺

Net ionic equation: Pb²⁺(aq) + SO₄^2-(aq) PbSO₄(s)

b) Reaction will occur when HClO (aq) and Sr(OH)₂ (aq) solutions are mixed and the balanced equation is:

2HClO(aq) + Sr(OH)₂(aq) Sr(ClO)₂(aq)+ 2H₂O(l)

Complete ionic equation:
2 HClO(aq) + Sr²⁺(aq) + 2 OH^-(aq) Sr²⁺(aq) + 2 ClO^-(aq) + 2 H₂O(l)

Spectator ion: Sr²⁺

Net ionic equation:
2 HClO(aq) + 2 OH^-(aq) 2 ClO^-(aq) + 2 H₂O(l)

Reaction is: Pb(NO3)2(aq) + 2KI(aq) ---> PbI2(s) + 2KNO3(aq) 2.0 ml of 0.250M Pb(NO3)2 and 7.0 ml of 0.250M KI A) In your experiment, one of the reagents was limiting and the other was in excess. Therefore after the lead(II)iodide precipitated from the solution, there were spectator ions left in the solution, and also the unreacted excess reagent. Assuming complete precipitation of lead (II) iodide, calculate the concentrations of each type of ion (Pb2+, K+, NO3-, I-) present in the...
