Questions about the Flame Tests poster

What’s on the Flame Tests poster?

A 7-row table: Ion · Colour. Metal ion and flame colour. Lithium — Crimson; Sodium — Yellow-orange; Potassium — Lilac; Calcium — Orange-red; Barium — Apple green; Copper(II) — Blue-green; Strontium — Red. Sodium's intense yellow masks everything else. Even trace contamination ruins a flame test, so the wire must be cleaned in acid.

Who is the Flame Tests poster for?

Flame Tests 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 Flame Tests poster?

Electrons are excited and drop back, emitting a characteristic wavelength. A wall chart earns its place by being glanceable from where the work is happening, so Flame Tests belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.

What other posters go with Flame Tests?
