What is the word equation for copper sulphate and zinc?
Zn(s) + CuSO4(aq) -> Cu(s) + ZnSO4 (aq). It’s a displacement reaction. It’s a redox reaction.
Is copper more reactive than zinc?
The metals that form positive ions by losing electrons more readily. A more reactive metal displaces a less reactive metal from salt solution. Therefore, zinc is more reactive than copper.
When a zinc rod is suspended in copper sulphate solution?
As zinc is more reactive than copper, zinc will displace copper from its solution and will start forming zinc sulphate solution. Number of changes can be seen when zinc rod is placed directly into the solution containing copper sulphate: The blue color of the solution will eventually fade and disappear after sometime.
Why can’t copper displace zinc?
In the reactivity series, zinc is more reactive than copper. A more reactive metal can replace a less reactive metal, but a less reactive metal cannot replace a more reactive metal. Thus, copper cannot displace zinc from its salt solution, while zinc can displace copper from its salt solution.
Why is zinc not very reactive?
The reason is that Zinc has a filled D-shell, which means that it is almost unique in having completely filled inner shells, with two electrons in the outer shell. All the n=1, n=2 and n=3 orbitals completely filled in Zn, and exactly 2 electrons very loosly bound in the n=4 orbitals.
What happens when zinc rod is suspended in feso4 solution?
ions to the elemental metal for the reason stated above), the blue colouration of the solution will fade and eventually disappear and copper metal will be deposited. So weight of zinc rod starts increasing as Copper will be deposited on the Zinc rod.
What will you observe if you place a zinc rod in copper sulphate solution?
Zinc is more reactive than copper. Due to this, it will undergo displacement reaction. When zinc rod is placed in the copper sulphate solution, it will displace copper from its solution and the brownish copper color will start depositng over the zinc rod.
Can copper displace zinc or lead from their salt solutions?
Copper is less reactive than zinc. Therefore, it cannot displace zinc from its salt solution.
Is copper displace zinc from zinc sulphate solution?
Considering option (C), Copper displaces zinc from zinc sulphate solution. Copper is less reactive than zinc and so placed below zinc in the reactivity or electron affinity series of metals. A metal which is less reactive, cannot displace a more reactive metal from a solution of its salt.
What’s the balanced chemical equation for zinc and copper sulfate?
Zinc is higher than copper on the electromotive series, so will react to displace the copper from copper sulfate. This reaction takes place in an aqueous solution. The balanced chemical reaction is Zn + CuSO4 = ZnSO4 + Cu. Classic single-replacement equation, w/ Zu replacing Cu in the Sulfate.. The zinc displaces the copper in the copper sulfate:
What is the word equation for lead + copper sulphate?
A more descriptive way to write it is the “ionic equation”: As you can see, the sulfate ion was not involved in the reaction, so we can write a more streamlined version that only includes the substances that actually react. This is called the “net ionic equation”.
What is the net ionic equation for copper?
Net ionic equation: Zn (s) + Cu 2+ (aq) –> Cu (s) + Zn 2+ (aq) 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.
How much copper sulfate do you need for single displacement reaction?
Pour about 250 mL of copper sulfate solution into each of the beakers. Fold the zinc strip in half over the glass rod.
