The Colour Chemistry of Gemstones – Precious Stones [Infographic]
A gemstone or gem (also called as precious stone or semi-precious stone, a fine gem, or jewel) is a piece of mineral, which, in cut and polish form, is used to make jewelry or other adornments. The colours of Gemstones – Precious Stones are affected by differences in chemical and atomic structure, leading to the absorption […]
Testing for Cations By Sodium Hydroxide & Ammonia Precipitates [Infographic]
Sodium Hydroxide (NaOH) solution or aqueous Ammonia solution can be added to the solutions containing metal ions in order to discern their identity. The colour precipitate from by the reaction can be used to determine the metal identity. In some cases, the precipitate dissolves in excess NaOH and Ammonia. In the following Test for Cations […]

Metal Ion Flame Test Colours [Infographic]
A flame test is an analytical procedure used by chemists to detect the presence of particular metal ions, based on the colour of the flame produce. When heated, the electrons in the metal ion gain energy and can jump into higher levels. Because this is energetically unstable, the electrons tend to fall back down to […]

Colours of Transition Metal Ions in Aqueous Solution [Infographic]
Transition Metals form coloured compounds and complexes. These colours can be vary depending on the charge on metal ion, and the number and type of groups of atoms (called ligands) attached to the metal ion. In aqueous solutions, the ions form colours with complexes. Electrons are arranged around the nucleus of the metal atom in orbitals, […]
