  • Ammonium chloride Wikipedia

    Ammonium chloride is an inorganic compound with the formula NH 4 Cl and a white crystalline salt that is highly soluble in water. Solutions of ammonium chloride are mildly acidic. Sal ammoniac is a name of the natural, mineralogical form of ammonium chloride. The mineral is commonly formed on burning coal dumps from condensation of coalderived gases. It is also found around some types of

  • Copper(II) hydroxide Wikipedia

    Copper(II) hydroxide can be produced by adding a sodium hydroxide to a dilute solution of copper(II) sulfate (CuSO 4 ܫH 2 O). The precipitate produced in this manner, however, often contains water and an appreciable amount of sodium hydroxide impurity. A purer product can be attained if ammonium chloride is added to the solution beforehand.

  • Snowfall in a vial MEL Chemistry

    Why does ammonium chloride precipitate? Ammonium chloride NH 4 Cl is well soluble in water, but its solubility is not endless – there's a moment, when ammonium chloride can no longer dissolve in water, the point of saturation. However, if we heat the solution properly, we can "force" all of the ammonium chloride, which is added to the

  • Magnesium Chloride and Copper Sulphate Questions?

    Jan 26, 2011 · Using copper, for making electrical wire, more electricity can flow over copper wires with less resistance than the alternative and cheaper aluminum. Copper saves a lot of electricity and power generation and pollution because of how much more efficient it is than aluminum wire. Same goes with solar heating panels.

  • Silver chloride and ammonia Gold Refining Forum

    Sep 23, 2016 · Second statement is correct. Ammonium chloride is weakly acidic, it being the salt of a strong acid (HCl) and a weak base (NH3). By adding base to ammonium chloride one will generate ammonia which will dissolve in the extra water giving an ammonia solution. Ammonia water is cheap though as it is used all the time in cleaning.

  • What kind of ions coprecipitate with chloride? Physics

    Nov 13, 2013 · Ammonium chloride is soluable in water, so it will not form a precipitate. Is the analysis below the question different from the question? Many ions coprecipitate with chloride, but the only one I see in the expanded question/analysis is silver.

  • Copper Precipitation Methods

    The copper precipitation by use of iron, scrap or sponge. 2. Electrolytic deposition. 3. The use of some gas or reagent by which the copper is obtained, usually in the form of an intermediate precipitate which requires further treatment. For example, the precipitation of the copper as Cu2Cl2 from chloride solutions with SO2 gas.

  • CHEM 101 Precipitation reactions

    Using solubility rules. The above table (or one similar to it) can be used to predict whether precipitation will occur when two solutions of different soluble ionic compounds are mixed. Example 1. For the two soluble compounds above, ammonium sulfate and sodium nitrate, will a precipitation occur upon mixing their aqueous solutions?

  • Protein Precipitation Using Ammonium Sulfate

  • Ammonium Chloride Corrosion in The Hendrix Group

    Ammonium Chloride Corrosion in Hydrotreating Units Description of Damage. Ammonium chloride corrosion is characterized by general or localized corrosion, often pitting, normally occurring under ammonium chloride or amine salt deposits, and often in the absence of a free water phase. The salts have a whitish, greenish or brownish appearance.

  • Does copper (II) sulfate + ammonium chloride have "no

    Oct 14, 2011 · However, double displacement reactions in solution can only occur if one of the products is insoluble. Both copper(II) chloride and ammonium sulfate are water soluble, so there's nothing to precipitate. In other words, mixing solutions of copper(II), sulfate, ammonium, and chloride ions will not cause any new substance to form. I hope that helps.
