What is the reaction of zinc and copper sulfate?
What is the reaction of zinc and copper sulfate?
Answer: When zinc is added to copper sulphate (CuSO4) solution due to more reactivity of zinc, copper is replaced by zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.
What type of reaction is the reaction between copper sulphate solution and zinc plate?
oxidation-reduction reaction
Hint: The reaction between zinc and copper sulphate solution is an oxidation-reduction reaction or we can say redox reaction, in which there is transfer of electrons takes place in between two species. During this reaction zinc sulphate solution is obtained.
What is displacement enthalpy?
The heat of displacement is the heat change when one mole of a metal is displaced from its salt solution by a more electropositive metal. The thermochemical reaction for the displacement reaction of copper by zinc can be represented as follows. Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s) ΔH = -210 kJ.
What type of reaction is the reaction between copper sulphate and zinc plate Class 8?
The reaction between copper sulfate, CuSO_4(aq), and zinc, Zn(s) is an oxidation-reduction reaction in which zinc reduces the copper.
Is the reaction between zinc and copper sulphate exothermic?
yes, metal Displacement reaction between Copper sulfate and Zn is spontaneous and is exothermic in nature.
Why the value of heat of displacement of copper by magnesium and zinc is different?
Magnesium and zinc are more electropositive than copper in the electrochemical series. Therefore, they will displace copper ions from copper (II) sulphate. The heat of displacement of copper ion from copper (II) sulphate by magnesium and zinc are different.
Are displacement reactions exothermic?
Displacement reactions are generally exothermic. This is because they occur spontaneously and are energetically favorable.
Is displacement always exothermic?
What happens when zinc displace copper from copper sulfate?
Displacement of zinc metal from copper (II) sulfate solution. Zinc is a more reactive metal than copper, thus it is able to displace copper metal from a solution containing copper (II) ions. The displacement reaction is a redox reaction, since both oxidation and reduction takes place at the same time.
What is the displacement reaction between zinc powder and CuSO4?
The displacement reaction between Zinc (s) powder and CuSO 4 solution is exothermic as heat is released to its immiediate surroundings. This is supported by the calculations of all the three trials. The Zinc (s) is in powder form which reacts faster with CuSO 4 solution as it has a larger surface area.
What is the reduction potential of copper II sulfate?
Since the copper(II) ion has substantially greater reduction potential (+0.15 V) than zinc ion (-0.76 V), it is readily reduced by zinc metal. The blue color of the aqueous copper(II) sulfate solution is due to the presence of the hexaaquacopper(II) ion in water.
What is the reaction between zinc and copper ion redox?
Single Displacement Reaction: Zinc and Copper (II) Ion REDOX. The solution is initially blue in color. A dark coating of copper metal appears on the zinc within two minutes and when 45 minutes have elapsed, there is a thick coat of copper metal powder on the zinc strip and the blue color of the solution has lightened considerably.
