  2. Aluminium hydride - Wikipedia

    en.wikipedia.org/wiki/Aluminium_hydride

    The allylic rearrangement reaction carried out using aluminium hydride is a S N 2 reaction, and it is not sterically demanding: [1] Phosphine reduction using aluminium hydride. Aluminium hydride will reduce carbon dioxide to methane with heating: [citation needed] 4 AlH 3 + 3 CO 2 → 3 CH 4 + 2 Al 2 O 3

  3. Standard solution - Wikipedia

    en.wikipedia.org/wiki/Standard_solution

    Standard solutions are generally prepared by dissolving a solute of known mass into a solvent to a precise volume, or by diluting a solution of known concentration with more solvent. [1] A standard solution ideally has a high degree of purity and is stable enough that the concentration can be accurately measured after a long shelf time. [2]

  4. Solution (chemistry) - Wikipedia

    Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.

  5. Sodium aluminate - Wikipedia

    en.wikipedia.org/wiki/Sodium_aluminate

    Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate is a white crystalline solid having a formula variously given as NaAlO 2, NaAl(OH) 4 (), [3] Na 2Al 2 O 3, or Na 2 Al 2 O 4.

    Vivarana is a subschool of classical Advaita Vedanta, established by Prakasatman (c. 1200–1300). [1] The name of the Vivarana-school is derived from Prakasatman's Pancapadika-Vivarana , a commentary on the Pancapadika by Padmapadacharya .

  7. Sodium bis (2-methoxyethoxy)aluminium hydride - Wikipedia

    en.wikipedia.org/wiki/Sodium_bis(2-methoxyethoxy...

    The trade name Red-Al refers to its being a reducing aluminium compound. It is used predominantly as a reducing agent in organic synthesis. The compound features a tetrahedral aluminium center attached to two hydride and two alkoxide groups, the latter derived from 2-methoxyethanol. Commercial solutions are colorless/pale yellow and viscous.

  8. Suspension (chemistry) - Wikipedia

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

    In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye , usually must be larger than one micrometer , and will eventually settle , although the mixture is only classified as a suspension when and while the particles have ...

  9. Buffer solution - Wikipedia

    en.wikipedia.org/wiki/Buffer_solution

    A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...
