  2. Triphenylmethanol - Wikipedia

    en.wikipedia.org/wiki/Triphenylmethanol

    Triphenylmethanol (also known as triphenylcarbinol and TrOH) is an organic compound. It is a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene. In strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable "trityl" carbocation ...

  3. Triphenylmethane - Wikipedia

    en.wikipedia.org/wiki/Triphenylmethane

    Triphenylmethane or triphenyl methane (sometimes also known as Tritan), is the hydrocarbon with the formula (C 6 H 5) 3 CH. This colorless solid is soluble in nonpolar organic solvents and not in water.

  4. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    Solid: A solid holds a definite shape and volume without the need of a container. The particles are held very close to each other. Amorphous solid: A solid in which there is no far-range order of the positions of the atoms. Crystalline solid: A solid in which atoms, molecules, or ions are packed in regular order.

  5. Solid solution - Wikipedia

    en.wikipedia.org/wiki/Solid_solution

    The propensity for any two substances to form a solid solution is a complicated matter involving the chemical, crystallographic, and quantum properties of the substances in question. Substitutional solid solutions, in accordance with the Hume-Rothery rules, may form if the solute and solvent have: Similar atomic radii (15% or less difference)

  6. Suspension (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Suspension_(chemistry)

    A suspension of liquid droplets or fine solid particles in a gas is called an aerosol. In the atmosphere , the suspended particles are called particulates and consist of fine dust and soot particles, sea salt , biogenic and volcanogenic sulfates , nitrates , and cloud droplets.

  7. Liquidus and solidus - Wikipedia

    en.wikipedia.org/wiki/Liquidus_and_solidus

    The solidus is the locus of temperatures (a curve on a phase diagram) below which a given substance is completely solid (crystallized). The solidus temperature specifies the temperature below which a material is completely solid, [2] and the minimum temperature at which a melt can co-exist with crystals in thermodynamic equilibrium.

  8. Triphenylene - Wikipedia

    en.wikipedia.org/wiki/Triphenylene

    It is a white or colorless solid. Preparation ... triphenylene has attracted attention as the core of discotic mesogen in liquid crystalline materials. [6]

    Crystalline benzoic acid shown here is a solid and an acid, but, in the context of this article, it is not a "solid acid", which are polymeric materials and typically stronger acids. Examples of inorganic solid acids include silico-aluminates ( zeolites , alumina , silico-aluminophosphate), and sulfated zirconia .
