It may be wise to check (using pH or litmus paper) that no acid remains. The copper from the copper oxide stays in the liquid as Cu 2+ ions. am a bit confused about the spectator ions we have also are we expecting to get OH-(aq) + H+(aq) ===> H2o (l) ??? A student investigated the reactions of copper carbonate and copper oxide with dilute hydrochloric acid. Oxide + Acid -> Salt + water. What does contingent mean in real estate? Forming copper(I) complexes (other than the one with water as a ligand) also stabalises the copper(I) oxidation state. (a) Predict the new compound formed which imparts a blue-green colour to solution. In order for a double replacement reaction to take place, you need the reaction to produce an insoluble compound that precipitates out of solution..

Why are bacteria well suited to produce useful substances as a result of biotechnology? Copper nitrate is time and a half. If pure hydrochloric acid is added to a sample of pure copper, there is essentially no reaction; the solution should not turn blue. What is the balanced equation of hydrochloric acid copper oxide. So, yes, copper will slowly dissolve in hydrochloric acid bath, especially if some 'seed' copper chloride is present. copper(I) oxide, the equation is Cu2O + 2 HCl => 2 CuCl + +rep Heating copper hydroxide produces copper oxide, CuO, a black solid. It can re­act with both acids and bases.
