Product description
- Using the ion-electron balance method (half-reaction method), complete the OVR equations. Specify the oxidizing agent and reducing agent. If necessary, remove the medium in which this reaction takes place. Make conjugated redox pairs; using the values of standard redox potentials, calculate the EMF and confirm the possibility of a spontaneous reaction. Will this reaction go to completion?
- Na2S Na2SO3 ... → S ...
SO2 I2 H2O → H2SO4 ...
