The exothermic reaction of hydrochloric acid with particulate copper occurs during the hydrogen production step in the thermochemical copper鈥揷hlorine water splitting cycle. In this paper, this chemical reaction is modeled kinetically, and a parametric study is performed to determine the influences of ...
Copper oxychloride is also produced by hydrolysis of copper(II) chloride solutions at pH's of 47. Various alkali can be used such as sodium carbonate (Agal'tsov et al., 1982) or ammonium, calcium, or sodium hydroxides (Feitknecht and Maget, 1949). The reaction with sodium hydroxide can ...
The third reaction takes advantage of the fact that Cu(OH)2 is thermally unstable. When heated, Cu(OH)2 decomposes (breaks down into smaller substances) into copper II oxide and water. When the solid CuO is reacted with sulfuric acid, the copper is returned to solution as an ion (Cu2...

How many grams of copper (II) Chloride are formed in the double replacement reaction of 1.1 g copper (II) oxide and excess hydrochloric acid? H2SO4 + 2NaOH = 2H2O + Na2SO4 How much of the excess reagent will remain after the reaction has been completed? SO3...
The invention relates to a method for preparing a nano Cu2-xSe array on a copper substrate by a hydrothermal process, which comprises the following steps: (1) polishing the surface of the copper substrate, soaking the copper substrate in concentrated hydrochloric acid, washing, and drying for ...
