Rule 1: The oxidation number of an element in its free (uncombined) state is zero — for example, Al(s) or Zn(s). This is also true for elements found in nature as diatomic (two-atom) elements: H2, O2, S8. Rule 2: The oxidation number of a monatomic (one-atom) ion is the same as the charge on the ion, for example: Na+, S2—
For reduction, the chart is read from left to right. For oxidation, the chart is read from right to left and the sign of the voltage is changed. If there are two possible oxidation reactions, the lowest one on the chart occurs. Corrosion of a metal is oxidation. Electrolysis uses electrical energy.
This acid-base chart includes the K a value for reference along with the chemical's formula and the acid’s conjugate base. The acid and base chart is a reference table designed to make determining the strength of acids and bases simpler. This chart is ideal for use in the lab or in the classroom.
