Now, we are going to study that. Add to both sides of the equation. Add and . Determining oxidation numbers from the Lewis structure (Figure 1a) is even easier than deducing it from the molecular formula (Figure 1b). The values 0.95 and 1.28 V are so called standard (redox) potentials, E°. Answered by Ishan J. Chemistry tutor. This is because chlorine is able to engage its d-orbital by hybridization, in which an electron in a lower energy level of may be an s-orbital or any other orbital below the d-orbital, reaches an excited state where it is promoted to a higher energy level which is the d-orbital. 3-D.
