Problem: Balance the following equation in basic conditions. Phases are optional.CoCl2+Na2O2 = Co(OH)3+Cl- +Na+(redox and oxidation reactions)

FREE Expert Solution

CoCl2 + Na2O2  Co(OH)3 + Cl- + Na+


Step 1. Separate the whole reaction into half-reactions

CoCl2  Co(OH)3 + Cl-                                          Na2O2 → Na+


Step 2. Balance the non-hydrogen and non-oxygen elements first

CoCl2  Co(OH)3 + 2 Cl-                                          Na2O2 → 2 Na+
