Which out of two zinc container or copper container can be used to store hydrochloric acid?

Which out of two zinc container or copper container can be used to store hydrochloric acid?

No you can’t, As per it is more reactive than Copper which could take place in displacement reaction due to a medium.

Why does the hydrochloric acid only dissolve the zinc and not the copper?

Solution : In displacement reaction, more reactive metal displaces less reactive metal. Since, zinc is more reactive than hydrogen it displaces hydrogen in dilute hydrochloric acid and copper is less reactive than hydrogen and hence cannot displace hydrogen in dilute hydrochloric acid.

What happens when you add dilute hydrochloric acid to zinc?

Metals with dilute acid 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.

How do zinc and copper differ in their reaction to hydrochloric acid?

Zinc reacts with hydrochloric acid to produce hydrogen gas because it’s more reactive than hydrogen, and thus displaces the latter from an acid. By comparison, copper cannot displace hydrogen from HCl because it’s less reactive than hydrogen. Zinc will reduce the hydrogen and get oxidized in the process.

Which of the following solution can be stored in copper vessel?

(iv) Can copper sulphate solution be stored in gold vessel? Silver nitrate solution can not be stored in a copper vessel. Copper sulphate solution can be stored in a zinc vessel.

Which solution can be kept in a copper vessel?

(d) H2O Copper does not react with water. So, its container can store H2O in it. Thus, HCl, solution and H2O can be kept in copper vessel but dil, HNO3 cannot be kept in copper vessel.

Why is copper not react with hydrochloric acid?

Copper is a less reactive metal, hence does not react with any acid. 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.

Does copper dissolve in hydrochloric acid?

Explanation: There will be no reaction. Copper is a very unreactive metal, and it does not react with hydrochloric acid.

Does copper react with hydrochloric acid?

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.

Is the reaction between zinc and hydrochloric acid exothermic?

The reaction is exothermic, and thus the reaction generates heat. When dilute hydrochloric acid is added to granulated zinc placed in a test tube, zinc metal is converted to zinc chloride and hydrogen gas is evolved in the reaction.

Which element zinc or copper reacted with the hydrochloric acid?

Commercial brass, an alloy of Zn and Cu, reacts with hydrochloric acid as follows: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) (Cu does not react with HCl.) When 0.5065 g of a certain brass alloy is reacted with excess HCl, 0.0985g of ZnCl2 is eventually isolated.

Which can be stored in CU container?

(c) Copper is less reactive than zinc so it does not react with solution. Therefore, it can be stored in copper container.

Why is copper preferred to store dilute hydrochloric acid?

In reactive series,the position of copper below hydrogen, so copper does not react with dilute hydrochloric acid. But zinc reacts dilute hydrochloric acid to form zinc (ii)chloride and hydrogen gas. Therefore,copper will be preferred to store dilute hydrochloric acid.

What happens when zinc metal is immersed in copper(II) sulfate solution?

When zinc metal is immersed in a solution of 0.1 M aqueous copper(II) sulfate solution copper metal plates out on the zinc. The solution is initially blue in color.

Which of the following substances cannot be kept in copper vessel?

Thus, HCl, solution and H2O can be kept in copper vessel but dil, HNO3 cannot be kept in copper vessel. (ii) Reactions of aluminium with (a) Dilute HCl Al reacts with dilute HCl, so it cannot be kept in aluminium container.

Why can’t zinc chloride be stored in an aluminium vessel?

Aluminium being more active metal than zinc displaces latter from its solution ,thus zinc chloride cannot be stored in aluminium vessel. ) layer which prevents further reaction.
