What happens when Zn reacts with CuSO4?
Answer: When zinc is added to copper sulphate (CUSO4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.
What are the products in the equation Zn CuSO4 ZnSO4 CU?
When Zinc (Zn) react with Copper Sulphate (CuSO4) to form Zinc Sulphate (ZnSO4) and Copper (Cu).
Is Zn CuSO4 ZnSO4 CU a redox reaction?
Zn2+ in ZnSO4 is +2. Oxidation number of Zn changes from 0 to +2, and the oxidation number of Cu goes from 2+ to 0. THis means, Zn is undergoing oxidation or being oxidized or acting as an reducing agent. Similarly, Cu2+ is undergoing reduction or being reduced or acting as an oxidizing agent.
Is Zn more reactive than CU?
Zinc displaces copper, and iron from their solutions. Zinc is more reactive than Cu and Fe metal.
Is Zn CuSO4 exothermic?
Zn(s) + CuSO4(aq) ZnSO4(aq) + Cu(s) An important aspect of these experiments is that they are exothermic. An exothermic reaction gives out heat as a source of energy.
What gas is produced from CuSO4 Zn?
The problem is that most copper sulphate is slightly acidic (residual H2SO4) so there is a reaction between the Zn(s) and residual H2SO4 that generates some hydrogen gas.
What is the Colour of copper sulphate?
Copper sulfate is a greenish-white crystalline solid; the pentahydrate is blue powder or granules, or ultramarine crystalline solid.
Why does Zn displace Cu from CuSO4?
Answer. it is called as single displacement reaction. reactivity of zinc metal is more than that of cu (copper) so it displace the copper from its solution of copper sulphate and forms zincsulphate.
Does cu2+ react with Zn?
In a redox reaction, the reactant that loses electrons (is oxidized) causes a reduction and is called a reducing agent. In the example above, zinc metal is the reducing agent; it loses two electrons (is oxidized) and becomes Zn2+ ion. Cu2+ ion gains two electrons (is reduced) to form copper metal.
Why is zinc more reactive than CU?
Why Zinc is more reactive than copper? Answer: We find, Zinc is placed higher than Copper in the Electro-chemical Series, since Zinc is more reactive than Copper. Now, the reason is that Zinc loses its valence electrons more easily than Copper to take part in a reaction.
What does reducing agent mean?
Reducing agent (also called a reductant or reducer) is an element or compound that loses (or “donates”) an electron to an electron recipient (oxidizing agent) in a redox chemical reaction. A reducing agent is thus oxidized when it loses electrons in the redox reaction.
Which is more electronegative Zn or Cu?
Copper is slightly more electronegative than zinc*. Thus, if you put the two metals next to each other (or if you connect them by a wire), some electrons will move from the zinc to the copper.
What is the least reactive metal?
The metals designated as the transition metals in the periodic table are much less reactive, and metals such as gold and platinum prop up the bottom of the series, exhibiting little in the way of chemical reaction with any everyday reagents.
