If excess zinc is added to a bluish green solution of copper (II) sulphate, and the excess zinc filtered off after completion of reaction, a colourless solution is obtained because
both zinc and copper are metals
the sulphate radical and the zinc ion are divalent
zinc is more electropositive than copper
both zinc and copper form depositive ions in solution
zinc is a reducing agent

Zn (s)+ CuSO4(aq)----> ZnSO4(aq) +Cu(s)
in the eqn above zinc is the reducing agent . It displaced Cu from its soln cos its more electroposive than copper.
Conclusion (C) is d correct answer . D could have been d answer if they wrote that zinc is the reducing agent , because copper in some case can be a reducing agent . Hope i helped

because zinc is more electro positive than copper, if you read periodicity very well then you will understand better, so the answer is c

explaination is needed please
Aside that there are some question that needed explain for better understanding esp. for chemistry
Elements high up in d electrochemical series displace d lower element in d electrochemical series 4rm their solution,so d correct answer is option D
please answer actually chose is not what I'm actually saying cuz I will choose the right answer then when I check it I'll see that what I chose is not what was given and I will not wrong like in English most of those things I that they are sharing wrong wrong there was not actually what I chose and now I'm seeing it in chemistry I'm not really happy about this cuz it's really reducing my score that I'm supposed to have
ans is C elements below in the electrochemical series are easily displaced from their solutions
let me give you some tips in electrochemical series
