The main use of copper(I) chloride is as a precursor to the fungicide copper oxychloride. For this purpose aqueous copper(I) chloride is generated by comproportionation and then air-oxidized: [12] Cu + CuCl 2 → 2 CuCl 4 CuCl + O 2 + 2 H 2 O → Cu 3 Cl 2 (OH) 4 + CuCl 2. Copper(I) chloride catalyzes a variety of organic reactions, as
The State Fair of Texas starts Sept. 29, kicking off 24 days of fair fun. Established in 1886 , the State Fair of Texas continues to promote Texas agriculture, education and community involvement ...
Predicting the color of a compound can be extremely complicated. Some examples include: Cobalt chloride is pink or blue depending on the state of hydration (blue dry, pink with water) so it is used as a moisture indicator in silica gel. Zinc oxide is white, but at higher temperatures becomes yellow, returning to white as it cools.
The Texas State Fair Football Showdown took place on the third weekend of the 2018 and 2019 fair and featured Southern and Texas Southern.

[12] [13] Copper(II) chloride reacts with several metals to produce copper metal or copper(I) chloride (CuCl) with oxidation of the other metal. To convert copper(II) chloride to copper(I) chloride, it can be convenient to reduce an aqueous solution with sulfur dioxide as the reductant: [8] 2 CuCl 2 + SO 2 + 2 H 2 O → 2 CuCl + 2 HCl + H 2 SO 4

The flame test carried out on a copper halide. The characteristic bluish-green color of the flame is due to the copper. A flame test is relatively quick test for the presence of some elements in a sample. The technique is archaic and of questionable reliability, but once was a component of qualitative inorganic analysis.
