  2. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    To create the solution, 11.6 g NaCl is placed in a volumetric flask, dissolved in some water, then followed by the addition of more water until the total volume reaches 100 mL. The density of water is approximately 1000 g/L and its molar mass is 18.02 g/mol (or 1/18.02 = 0.055 mol/g). Therefore, the molar concentration of water is

  3. Ammonium hexachloroplatinate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_hexachloroplatinate

    The compound consists of separate tetrahedral ammonium cations and octahedral [PtCl 6] 2− anions.It is usually generated as a fine yellow precipitate by treating a solution of hexachloroplatinic acid with a solution of an ammonium salt. [2]

    The actual memory of water can be measured experimentally and is found to be around 50 femtoseconds, which is 0.00000000000005 seconds. [38] Generally considered to be pseudoscience by the scientific community, one disputed study into the so-called memory of water, conducted by Jacques Benveniste , claims to have demonstrated that water can be ...

  5. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry. Hydrochloric acid, the aqueous solution of hydrogen chloride, is also commonly given the formula HCl.

  6. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    They range from those of water at very low concentrations approaching 0% HCl to values for fuming hydrochloric acid at over 40% HCl. [ 31 ] [ 32 ] [ 33 ] Hydrochloric acid as the binary (two-component) mixture of HCl and H 2 O has a constant-boiling azeotrope at 20.2% HCl and 108.6 °C (381.8 K; 227.5 °F).

  7. Sample preparation in mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Sample_preparation_in_mass...

    Sample preparation for mass spectrometry is used for the optimization of a sample for analysis in a mass spectrometer (MS). Each ionization method has certain factors that must be considered for that method to be successful, such as volume, concentration , sample phase, and composition of the analyte solution.

  8. Hydrochloride - Wikipedia

    en.wikipedia.org/wiki/Hydrochloride

    In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine). An alternative name is chlorhydrate, which comes from French. An archaic alternative name is muriate, derived from hydrochloric acid's ancient name: muriatic acid.

  9. Aqua regia - Wikipedia

    en.wikipedia.org/wiki/Aqua_regia

    Aqua regia (/ ˈ r eɪ ɡ i ə, ˈ r iː dʒ i ə /; from Latin, "regal water" or "royal water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. [b] Aqua regia is a fuming liquid. Freshly prepared aqua regia is colorless, but it turns yellow, orange or red within seconds from the formation of nitrosyl ...
