Why blue colour of CuSO(4) solution gets...

Why blue colour of `CuSO_(4)` solution gets discharged when zinc rod is dipped in it ? Given, `E_(Cu^(+2)//Cu)^(@)=0.34 V and E_(Zn^(+2)//Zn)^(@)=-0.76V`

Text Solution

Verified by Experts

Here reduction potential of `Cu gt Zn`. So, `Cu^(+2)(aq)` ions reduced to Cu(s).
