Does copper or zinc react with HCl?
Zinc metal reacts with hydrochloric acid, generating hydrogen gas. However, when a strip of nickel, copper, platinum or lead is placed in hydrochloric acid, no reaction is observed….Multimedia.

Which type of reaction is Zn 2hcl → ZnCl2 H2?
displacement reactions
In displacement reactions element present in the solution is displaced by another reactive element. In this case, Zinc is displacing Hydrogen from HCl. Thus, this is an example of a displacement reaction.
What happens when Cu reacts with HCl?
Yes, it is obvious that copper will not react with hydrochloric acid for the simple reason it’s below hydrogen in the reactivity series. So, copper cannot replace the hydrogen in HCl to form CuCl2 . Hence, when copper (Cu) reacts with hydrochloric acid (HCl) there will be no reaction.
Why does zinc react with HCl and copper does not?
Zinc is more reactive than copper as Zinc is placed above Hydrogen and Copper is placed below hydrogen in the activity series of metals. Because of this Zinc reacts with HCl whereas Copper will not react.
Is 2hcl Zn → H2 ZnCl2 a single replacement reaction?
Explanation: The equation has one reactant’s atom(s) given to the other reactant, causing a single replacement.
What type of reaction is Zn cucl2 → ZnCl2 CU?
1 Answer. This is a redox reaction in which the oxidation states of the metals clearly change.
Is Zn 2hcl → ZnCl2 H2 a redox reaction?
Zn (s) + 2 HCl (aq) –→ ZnCl2 (aq) + H2 (g) In the reaction shown above, is Zn being oxidized or reduced? Comment to Instructor: Correct answer is 1. oxidized.
What is the product of Zn 2hcl?
The products of the reaction are aqueous zinc chloride and hydrogen gas.
What type of reaction is Cu and HCl?
Explanation: There will be no reaction. Copper is a very unreactive metal, and it does not react with hydrochloric acid. It is above copper in a metal reactivity series, so copper cannot replace the hydrogen in HCl to form CuCl2 .
Why does Cu not react with HCl?
But Cu does not react with HCl because the reduction potential of Cu is higher than that of hydrogen. Only metals which have their reduction potential less than that of hydrogen react with non – oxidising acids. i.e. Hence, the reaction is not feasible.
What happens when zinc reacts with HCl?
When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. We can measure the rate of the reaction by measuring how fast the reaction produces hydrogen.
What will happen when copper and zinc is mixed?
Copper(II) oxide and zinc metal react together in an exothermic reaction to produce zinc oxide and copper. By observing this reaction and its products, and noting the difference in reactivity between zinc and copper, students can familiarise themselves with the idea of competiton reactions.
What is a chemical reaction HCl with zinc?
When zinc reacts with hydrochloric acid, the reaction bubbles vigorously as hydrogen gas is produced. The production of a gas is also an indication that a chemical reaction is occurring.
Is ZnCl2 –> ZnCl2 a redox reaction?
Explanation: The given reaction is certainly a redox reaction.
What type of reaction occurs between zinc and HCl?
Hydrogen Replacement
Hydrogen Replacement Many metals react easily with acids and when they do so, one of the products of the reaction is hydrogen gas. Zinc reacts with hydrochloric acid to produce aqueous zinc chloride and hydrogen (figure below). In a hydrogen replacement reaction, the hydrogen in the acid is replaced by an active metal.
What type of chemical reaction will take place if a piece of zinc is added to an aqueous solution of cupric chloride?
When a piece of zinc is added to an aqueous solution of cupric chloride Redox reaction takes place. Redox reaction is a reaction where both oxidation and reduction take place.
