HNO3 is an oxidizing agent when Cu reacts with this cu act as reducing agent and certianly cu does not replac H2 from this but reduce HNO3 to either NO or NO2 . 2 The structure of copper consists of negative ions in a lattice. . Copper metal will not oxidize when put in H+ ions, it will reduce because it is a stronger oxidizing agent. . Cu + 2H+ --> Cu++ + H2 is not possible on the other hand reverse reaction is possible i.e. This is because the reduction potential for water is only -0.83 V compared to -2.71 V for the reduction of sodium ions. Balancing chemical equations. The reaction converts all of the aluminum and zinc in the alloy to aluminum chloride and zinc chloride in addition to producing hydrogen gas. Therefore that chlorine atom does not reduce to show oxidizing acid characteristics. Also, copper can react with H2SO4 in the presence of oxygen. .Eo = +0.00 V, Cu + 2H+ ==> Cu2+ + H2 .Eo cell = -0.34 V .

H2SO4 is also oxidizing agent and Cu reduces this into SO2 . At read heat, copper metal and oxygen react to form Cu 2 O. Magnesium Copper does not react with dilute hydrochloric acid at all. (2) (c) Suggest one reason why the redox reaction between chlorine and water does not normally occur in the absence of light. The displacement reaction from CuSO4 to FeSO4 occurs because although both metals readily react with SO4 to form an ionic salt, iron has a lower electronegativity than copper and has a greater attraction to the oppositely charged SO4 ion. Reaction with dilute Acids: Metal + Dilute Acid → Salt + H2. How many moles of hydrogen gas are needed to produce 0.359 moles of water? The same goes for Cu reacting with an acid.

Thanks in advance! . 1 Copper is malleable because layers of ions are in fixed positions and cannot move. Z n gives H 2 gas with H 2 S O 4 and H C l but not with H N O 3 because: A. Yahoo ist Teil von Verizon Media. Thermodynamic properties of substances The solubility of the substances Periodic table of elements. Hence it does not react with copper metal at all. This shows that copper is even less reactive than iron. The reactivity series shows metals in order of reactivity. On the other side, strong sulfur has been oxidized by hydrogen sulfide (H2S).
