WebCurrently, lithium-iodine cells are commonly used to power pacemakers and have replaced zinc-mercury cells. Table 1 provides the operating cell potential, E, for each cell. Table 2 provides the standard reduction potentials for several half-reactions related to zinc-mercury and zinc-air cells. WebAlthough many of the half cells are written for multiple-electron transfers, the tabulated potentials are for a single-electron transfer. All of the reactions should be divided by the …

WebSince propidium iodide is not permeant to live cells, it is also commonly used to detect dead cells in a population. PI binds to DNA by intercalating between the bases with little or no sequence preference. In aqueous solution, the dye has excitation/emission maxima of … WebWhat are the half reactions for the redox reaction between SO A 2 and iodine? The relevant chemical equation: SO A 2 + H A 2 O + I A 2 H A 2 SO A 4 + 2 HI This is what I think it is, not sure if it's correct. Oxidation: SO A 2 + 2 H A 2 O SO A 4 A 2 − + 4 H A + + 2 e A − Reduction: I A 2 + 2 e A − 2 I A − Share Save Helvetica 12px Comment WebIodine (I2) gains electrons and gets reduced to iodide ions (I-). This is the reduction half-reaction: I2 + 2e- → 2I- So, the two half-reactions required to represent the reaction between ascorbic acid and iodine are: Oxidation half-reaction: C6H8O6 → C6H6O6 + 2H+ + 2e- Reduction half-reaction: I2 + 2e- → 2I- Recommended Videos 01:40 pdf warner bros
