  2. Copper(I) iodide - Wikipedia

    en.wikipedia.org/wiki/Copper(I)_iodide

    Copper(I) iodide reacts with mercury vapors to form brown copper(I) tetraiodomercurate(II): 4 CuI + Hg → (Cu +) 2 [HgI 4] 2− + 2 Cu. This reaction can be used for the detection of mercury since the white CuI to brown Cu 2 [HgI 4] color change is dramatic. Copper(I) iodide is used in the synthesis of Cu(I) clusters such as [Cu 6 I 7] −. [10]

  3. Catalytic heater - Wikipedia

    en.wikipedia.org/wiki/Catalytic_heater

    The catalytic heater is contained within the package which is usually made out of stainless steel. Instrument gas and pilot preheating regulators are only used for freeze protection, and to heat up the gas before it reaches the pilot. It can also be used to heat a stream of gas that is used for measurement or instrumentation. Space heating is a ...

    en.wikipedia.org/wiki/Gas_heater

    Upright non-flued liquefied petroleum gas heater, 1970s A wall mounted gas heater that runs on either propane or natural gas. A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or ...

    en.wikipedia.org/wiki/Fast-ion_conductor

    Upon heating the solid to 146 °C, this material adopts the alpha-polymorph. In this form, the iodide ions form a rigid cubic framework, and the Ag+ centers are molten. The electrical conductivity of the solid increases by 4000x. Similar behavior is observed for copper(I) iodide (CuI), rubidium silver iodide (RbAg 4 I 5), [9] and Ag 2 HgI 4.

    Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).

  7. History of manufactured fuel gases - Wikipedia

    The gas-works and adjacent district would smell of rotten eggs when the gas-works was producing gas; The gas, upon burning, would form sulfur dioxide, which would be quickly oxidized to sulfur trioxide, and subsequently would react with the water vapor produced by combustion to form sulfuric acid vapour. In a dwelling-house, this could lead to ...

  8. Iodide - Wikipedia

    en.wikipedia.org/wiki/Iodide

    The low solubility of silver iodide and lead iodide reflects the covalent character of these metal iodides. A test for the presence of iodide ions is the formation of yellow precipitates of these compounds upon treatment of a solution of silver nitrate or lead(II) nitrate. [2] Aqueous solutions of iodide salts dissolve iodine better than pure ...
