(b) Write a balanced chemical equation of the reaction which takes place. These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen). Note that if this is the case, you would not expect to see any bubbling on the copper, as copper (II) oxide will react with hydrochloric acid to form copper (II) chloride and water.

Pour the cool residue into a 100 cm 3 beaker and add a little dilute hydrochloric acid to dissolve the zinc oxide (and also any unreacted zinc and copper oxide), warming if necessary. Registered in England and Wales no. Add powdered insoluble reactant to some acid in a beaker, one spatula at a time, stirring to mix. There are no media in the current basket. When dilute hydrochloric acid to copper oxide powder, blue green colour is imparted due to the formation of copper chloride C u C l 2 . A student investigated the reactions of copper carbonate and copper oxide with dilute hydrochloric acid. The formation of cupric chloride results in the change in the colour from black to blusih green. Copper (II) oxide reacts with hydrochloric acid. GIPHOTOSTOCK / SCIENCE PHOTO LIBRARY METHOD (b) Reacting an acid with a metal or with an insoluble base to give a soluble salt e.g. the Terms and Conditions. 6b. c. Copper chloride - is produced when copper oxide reacts with hydrochloric acid. Add an answer or comment. ..... (1) (b) Write a balanced symbol equation for the reaction of dilute hydrochloric acid with calcium oxide. Copper oxide is a weak base, and it easily reacts with HCl forming soluble copper (II) chloride and water. The copper in the solution can be recovered by cementation from a sulfate bath.
