Question:

In acidic solution, the bromate ion can be used to react with anumber of metal ions. One such reaction is

BrO3?(aq)+Sn2+(aq)?Br?(aq)+Sn4+(aq)

Since this reaction takes place in acidicsolution, H2O(l) and H+(aq) will be involved inthe reaction. Places for these species are indicated by the blanksin the following restatement of the equation:

BrO3?(aq)+Sn2+(aq)+ ????Br?(aq)+Sn4+(aq)+ ???

1. What are the coefficients of the reactants and products inthe balanced equation above? Remember toinclude H2O(l) and H+(aq) in the appropriateblanks. Your answer should have six terms.

Enter the equation coefficients in order separated by commas(e.g., 2,2,1,4,4,3). Include coefficients of 1, as required,for grading purposes.

Potassium permanganate, KMnO4, is a powerful oxidizingagent. The products of a given redox reaction with the permanganateion depend on the reaction conditions used. In basic solution, thefollowing equation represents the reaction of this ion with asolution containing sodium iodide:

MnO4?(aq)+I?(aq)?MnO2(s)+I2(aq)

Since this reaction takes place in basicsolution, H2O(l) and OH?(aq) will be shown inthe reaction. Places for these species are indicated by the blanksin the following restatement of the equation:

MnO4?(aq)+I?(aq)+ ????MnO2(s)+I2(aq)+ ???
