Question

In acidic solution the sulfate ion can be used to react with a number of metal ions. One such reaction is SO_4^2 (aq) + Sn^2+ (aq) rightarrow H_2SO_2(aq) + Sn^4+ (aq) Since this reaction takes place in acidic solution H_2O(1) and H^+ (aq) will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation SO_4^2 (aq) + Sn^(aq) + rightarrow H_2SO_3(aq) + Sn^+ (aq) + What are the coefficients of the reactants and products . In the balanced equation above? Remember to include H_2O(1) and H (aq) in the appropriate blanks. You answer should have six terms Enter the equation coefficients in order separated by commas Include coefficients of 1 as required, for grading purposes. Potassium permanganate KMnO_4 is a powerful oxidizing. The products of a given redox reaction the permanganate ion depend on the reaction condition used. In basic solution the following equation represents the reaction of the ion with a solution containing sodium MnO_4 (aq) + I (aq) rightarrow MnO_2(s) + I_2(aq) Since this reaction takes place in basic solution H_2O(I) and OH (aq) will be shown in the reaction Places for these species are indicated by the blanks the following restatement of the equation MnO_4 (aq) + I (aq) + MnO_2 + I_2 (aq) +

Explanation / Answer

A) Sn2+(aq) + SO42-(aq) 4H+ ---> H2SO3(aq) + Sn4+(aq) + H2O(l)

B) 2MnO4-(aq) + 6I-(aq) + 4H2O(l) ------> 2MnO2(s) + 3I2(aq) + 8OH-(aq)
