    Note, however, that the use of yellow ( ) for sulfur is not advised as it can cause accessibility problems on a white background. Within a given article, diagrams should be consistent, which means in most cases they should use black and white except as highlighting to emphasize a particular point in specific diagrams.

    en.wikipedia.org/wiki/Piper_diagram

    A Piper diagram is a graphical representation of the chemistry of a water sample or samples. The cations and anions are shown by separate ternary plots. The apexes of the cation plot are calcium, magnesium and sodium plus potassium cations. The apexes of the anion plot are sulfate, chloride and carbonate plus hydrogen carbonate anions.

  7. Solvatochromism - Wikipedia

    en.wikipedia.org/wiki/Solvatochromism

    In chemistry, solvatochromism is the phenomenon observed when the colour of a solution is different when the solute is dissolved in different solvents. [1] [2] Reichardt's dye dissolved in different solvents. The solvatochromic effect is the way the spectrum of a substance (the solute) varies when the substance is dissolved in a variety of ...

  8. MXenes - Wikipedia

    en.wikipedia.org/wiki/MXenes

    MXenes adopt three structures with one metal on the M site, as inherited from the parent MAX phases: M 2 C, M 3 C 2, and M 4 C 3.They are produced by selectively etching out the A element from a MAX phase or other layered precursor (e.g., Mo 2 Ga 2 C), which has the general formula M n+1 AX n, where M is an early transition metal, A is an element from group 13 or 14 of the periodic table, X is ...

  9. Cis–trans isomerism - Wikipedia

    en.wikipedia.org/wiki/Cis–trans_isomerism

    Very often, cis–trans stereoisomers contain double bonds or ring structures. In both cases the rotation of bonds is restricted or prevented. [4] When the substituent groups are oriented in the same direction, the diastereomer is referred to as cis, whereas when the substituents are oriented in opposing directions, the diastereomer is referred to as trans.
