Question
Please answer the following question. pay attention to the instructions and hint.
HINT:
Excess preoxidation reagents must be removed prior to a redox titration. S2O82?, Ag3 , and H2O2 can all be destroyed through boiling. In order to complete the reactions, determine what the products of the boiling reactions are. Then, use whole number coefficients to balance the reactions.
Coplete and balance tha boiling reactions below that are used to destroy preoxidizing reagents. Use whole number coefficients.Explanation / Answer
1) S2O8-2 + 2H2O ----> 4SO4-2 + O2 + 4H+
2) 2H2O2 ----> 2H2O + O2
3) 2Ag+3 + H2O ----> Ag2O + 2H+
