Common Laboratory Chemicals in Reagent Bottles - Visual Reference Guide #176560 (License: Personal Use)

This illustration displays five common inorganic compounds stored in classic glass reagent bottles, each filled with a uniquely colored solution: orange K₂Cr₂O₇ (potassium dichromate), yellow FeCl₂ (iron(II) chloride), green NiSO₄ (nickel(II) sulfate), blue CuSO₄ (copper(II) sulfate), and violet Cr(NO₃)₃ (chromium(III) nitrate). The labels follow standard chemical nomenclature, making it ideal for educational or laboratory safety contexts. The vibrant hues help students and technicians quickly identify substances by appearance.

Used in chemistry education, lab manuals, safety posters, and online science resources to teach chemical identification, colorimetric analysis, or storage protocols; matches user intent for visual learning, lab preparation, or hazard recognition.
