The standard reduction potentials in table 12.1 would predict that acids (represented by H+(aq) or H3O+) can oxidise certain metals, such as Fe, Zn, Sn and Mg (see figure 12.17), but not other metals, such as Ag, Cu and Au.

[whats-in-a-sentence]

Table 12.1 lists values obtained for some typical half-reactions. (...) Table 12.1 shows that:

Substances located to the left of the double arrows are oxidising agents, because they become reduced when the reactions proceed in the forward direction.

The strongest oxidising agents are those most easily reduced, and they are located at the top left of the table (e.g. F2).

Substances located to the right of the double arrows are reducing agents; they become oxidised when the reactions proceed from right to left.

The strongest reducing agents are those found at the bottom right of the table (e.g. Li).

We can use the data in table 12.1 to show that we obtain the same spontaneous reaction regardless of how the cell diagram is written. (...) One of the goals of chemistry is to predict reactions. This can be done for redox reactions – whether they occur in a galvanic cell or just in a container with all the chemicals combined in one reaction mixture – using the half-reactions and standard reduction potentials in table 12.1. (...) The reactants and products of spontaneous redox reactions are easy to spot when reduction potentials are listed in order of most positive to least positive (most negative), as in table 12.1. (...) If you look at the location of lithium in the table of reduction potentials (table 12.1), you will see that it has the most negative reduction potential of any metal.

Improve Plant Health & Nutrients with Swales This is something of an update on my swale construction, but also some thoughts on facultative anaerobes (which I kept calling functional anaerobes in the video) and soil eh, also called reduction potential or redox.
