What’s on the Redox poster
A 8-row table: Rule · Value.
Rules for assigning oxidation numbers.
- Element in its standard state — 0
- Monatomic ion — Its charge
- Oxygen, usually — −2
- Oxygen in peroxides — −1
- Hydrogen with non-metals — +1
- Hydrogen with metals — −1
- Group 1 / Group 2 — +1 / +2
- Sum in a neutral compound — 0
The oxidising agent is itself reduced, and vice versa. That reversal is the commonest exam trap.
Questions about the Redox poster
- What’s on the Redox poster?
- A 8-row table: Rule · Value. Rules for assigning oxidation numbers. Element in its standard state — 0; Monatomic ion — Its charge; Oxygen, usually — −2; Oxygen in peroxides — −1; Hydrogen with non-metals — +1; Hydrogen with metals — −1; Group 1 / Group 2 — +1 / +2; Sum in a neutral compound — 0. The oxidising agent is itself reduced, and vice versa. That reversal is the commonest exam trap.
- Who is the Redox poster for?
- Redox belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning general chemistry can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Redox poster?
- OIL RIG. Oxidation Is Loss, Reduction Is Gain — of electrons. A wall chart earns its place by being glanceable from where the work is happening, so Redox belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Redox?
- Acids & Bases, Atomic Structure and Balancing Equations sit alongside Redox in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Acids & BasesAtomic StructureBalancing Equations
- Is the Redox poster free to download and print?
- Yes. Redox downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Redox poster print at?
- Redox is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Redox loses nothing.Printing guide
