  2. Gas/oil ratio - Wikipedia

    en.wikipedia.org/wiki/Gas/oil_ratio

    The gas/oil ratio (GOR) is the ratio of the volume of gas ("scf") that comes out of solution to the volume of oil — at standard conditions. In reservoir simulation gas/oil ratio is usually abbreviated . A point to check is whether the volume of oil is measured before or after the gas comes out of solution, since the remaining oil volume will ...

  3. Zinc hydroxide - Wikipedia

    en.wikipedia.org/wiki/Zinc_hydroxide

    Zn 2+ + 2 OH − → Zn(OH) 2. The initial colorless solution contains the zincate ion: Zn(OH) 2 + 2 OH − → Zn(OH) 4 2−. Zinc hydroxide will dissolve because the ion is normally surrounded by water ligands; when excess sodium hydroxide is added to the solution the hydroxide ions will reduce the complex to a −2 charge and make it soluble.

  4. Zinc sulfate - Wikipedia

    en.wikipedia.org/wiki/Zinc_sulfate

    Zn + H 2 SO 4 + 7 H 2 O → ZnSO 4 ·7H 2 O + H 2. Pharmaceutical-grade zinc sulfate is produced by treating high-purity zinc oxide with sulfuric acid: ZnO + H 2 SO 4 + 6 H 2 O → ZnSO 4 ·7H 2 O. In aqueous solution, all forms of zinc sulfate behave identically. These aqueous solutions consist of the metal aquo complex [Zn(H 2 O) 6] 2+ and SO ...

  5. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    The molar ratio allows for conversion between moles of one substance and moles of another. For example, in the reaction 2 CH 3 OH + 3 O 22 CO 2 + 4 H 2 O. the amount of water that will be produced by the combustion of 0.27 moles of CH 3 OH is obtained using the molar ratio between CH 3 OH and H 2 O of 2 to 4.

  6. Sulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Sulfuric_acid

    Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H2SO4. It is a colorless, odorless, and viscous liquid that is soluble with water.

  7. Neutralization (chemistry) - Wikipedia

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

    Ba(OH) 2 + 2 H + → Ba 2+ + 2 H 2 O. The same equation relating the concentrations of acid and base applies. The concept of neutralization is not limited to reactions in solution. For example, the reaction of limestone with acid such as sulfuric acid is also a neutralization reaction. [Ca,Mg]CO 3 (s) + H 2 SO 4 (aq) → (Ca 2+, Mg 2+)(aq) + SO ...

  8. Amphoterism - Wikipedia

    en.wikipedia.org/wiki/Amphoterism

    The water molecule is amphoteric in aqueous solution. It can either gain a proton to form a hydronium ion H 3 O +, or else lose a proton to form a hydroxide ion OH −. [5] Another possibility is the molecular autoionization reaction between two water molecules, in which one water molecule acts as an acid and another as a base.

  9. Metal ions in aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Metal_ions_in_aqueous_solution

    A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M (H 2 O) n] z+. The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table. Lanthanide and actinide aqua ions have higher solvation numbers ...
