Metals to the right of hydrogen in the electrochemical series, such as copper, silver and gold, do not react. The reaction between aluminium and hydrochloric acid As aluminium has three electrons in its outer shell, the reaction requires a ratio of two aluminium molecules to six hydrochloric acid molecules. Copper will stay in the reduced form, Cu, rather than losing electrons to go to an oxidized form, Cu+ or Cu2+. ! For this type of reaction to occur, the reduction potential of the reactant receiving the electrons must be lower than the reduction potential of the reactant giving up electrons. It will take about one week for Cu to react with HCl to form copper chloride CuCl2. All Rights Reserved. ! You can think of this happening in two stages. Sulfuric acid has a medium oxidizing ability and will dissolve copper over time. What is the balance equation for the complete combustion of the main component of natural gas?

Copper and mercury metal does not react with dilute hydrochloric acid as it comes after hydrogen in the activity series, i.e., they can't replace hydrogen from hydrochloric acid.. This means that is has a higher potential to be reduced (gain electrons) and is therefore less likely to be oxidized (lose electrons), which is what would need to happen for it to displace hydrogen.  For the sake of discussing the reaction, here's what the equation would look like if the reaction did take place: `2Cu + 2HCl -> 2CuCl + H_2` , E = 0.159 V. Both of these reactions have a positive standard reduction potential (E) compared to hydrogen, which is zero volts. Log in here.

But, concentrated sulphuric acid is an oxidising agent. In order for a metal to displace hydrogen from HCl it must have a negative standard reduction potential, which means that it needs to be below hydrogen on the activity series. When did sir Edmund barton get the title sir and how? Metallic zinc's activity is high enough to allow it to react with HCl, which produces H2 gas and the compound zinc chloride, or ZnCl2, explains Dr. Martin Silberberg in his book “Chemistry: The Molecular Nature of Matter and Change. #1 Will Copper sulfate react with hydrochloric acid?
