What’s on the Group 2 poster
A 5-row table: Compound · Down the group.
The two opposing solubility trends.
- Hydroxides — Solubility increases
- Sulfates — Solubility decreases
- Reactivity with water — Increases
- Ionisation energy — Decreases
- Thermal stability of carbonates — Increases
Barium sulfate is insoluble, which is why acidified barium chloride is the test for sulfate ions — and why it is safe as a medical 'meal'.
Questions about the Group 2 poster
- What’s on the Group 2 poster?
- A 5-row table: Compound · Down the group. The two opposing solubility trends. Hydroxides — Solubility increases; Sulfates — Solubility decreases; Reactivity with water — Increases; Ionisation energy — Decreases; Thermal stability of carbonates — Increases. Barium sulfate is insoluble, which is why acidified barium chloride is the test for sulfate ions — and why it is safe as a medical 'meal'.
- Who is the Group 2 poster for?
- Group 2 belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning inorganic can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Group 2 poster?
- Hydroxide solubility increases down the group; sulfate solubility decreases. A wall chart earns its place by being glanceable from where the work is happening, so Group 2 belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Group 2?
- Catalysts, Complex Ions and Electrolysis sit alongside Group 2 in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.CatalystsComplex IonsElectrolysis
- Is the Group 2 poster free to download and print?
- Yes. Group 2 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 Group 2 poster print at?
- Group 2 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 Group 2 loses nothing.Printing guide
