Acidic solution
In acidic solution, the sulfate ion can be used to react with a number of metal ions. One such reaction is
SO42−(aq)+Sn2+(aq)→H2SO3(aq)+Sn4+(aq)SO42−(aq)+Sn2+(aq)→H2SO3(aq)+Sn4+(aq)
Since this reaction takes place in acidic solution, H2O(l)H2O(l) and H+(aq)H+(aq) will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:
SO42−(aq)+Sn2+(aq)+ –––→H2SO3(aq)+Sn4+(aq)+ –––
Question A
What are the coefficients of the reactants and products in the balanced equation above? Remember to include H2O(l)H2O(l) and H+(aq)H+(aq) in the appropriate blanks. 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.
B part
Potassium permanganate, KMnO4KMnO4, is a powerful oxidizing agent. The products of a given redox reaction with the permanganate ion depend on the reaction conditions used. In basic solution, the following equation represents the reaction of this ion with a solution containing sodium fluoride:
MnO4−(aq)+F−(aq)→MnO2(s)+F2(aq)MnO4−(aq)+F−(aq)→MnO2(s)+F2(aq)
Since this reaction takes place in basic solution, H2O(l)H2O(l) and OH−(aq)OH−(aq) will be shown in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:
MnO4−(aq)+F−(aq)+ –––→MnO2(s)+F2(aq)+ –––
question 2
What are the coefficients of the reactants and products in the balanced equation above? Remember to include H2O(l)H2O(l) and OH−(aq)OH−(aq) in the blanks where appropriate. 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.
