Question
Predict what will happen (write a balanced equation if possible) When aqueous solutions of SnCl2 and KBr are combined. Explain in words how you made your prediction, using values of Ecell as appropriate. Thanks!Explanation / Answer
K+(aq) + e- -----> K(s) -2.93 Sn4+(aq) + 2 e- -----> Sn2+(aq) +0.13 Sn2+(aq) + 2 e- -----> Sn(s) -0.14 Br2(l) + 2?e- ---> 2?Br- +1.066 Look at the above reduction potential there is no possibility of oxidation or reduction in the given reagent and therefore, it will be simply double displacement reaction : SnCl2 + KBr --> SnBr2 + KCl
