`Cu^(2+)+ 2e rarr Cu` and `Cu-Ze rarr Cu6(2+)`. Which one occurs at cathod?

The electrode potential for Cu^(2+)(aq)+e rarr Cu^(+)(aq) and Cu^(+)(aq)+e rarr Cu(s) are 0.15V and 0.50V respectively. The value of E_(Cu^2+)|Cu^(@) will be -

Between Cu^(2+) and Fe^(2+) , which one is more paramagnetic?

Out of Cu^(2+) and Cu^(+) , which ion is unstable in aqueous solution and why?

Cu_(2)S is black and Cu_(2)O is red through Cu^(+) has no unpaired electrons and is colourless.

On passing C ampere of current for time ‘t' sec through 1L of 2 (M) CuSO_4 solution (atomic weight of Cu 63.5), the amount ‘m’ of Cu (in g) deposited on cathode will be cathode will be

The reaction H_(2)(g)+Cu^(2+)(aq)rarr Cu(s)+2H^(+)(aq) occurs in a galvanic cell. Identify cathode and anode of the cell and write the reaction that occur at the electroes.

Zn(s)+ Cu^(2+) rarr Zn^(2+) +Cu(s) in this reaction which is oxidant and which is reductant?

Consider the following galvanic cell given below- Cu|Cu^(2+)||Cl^(-)|Cl_(2) , Pt. Write the reactions that occur at anode and cathode.

Arrange K^(+), Zn^(2+), H^(+), Cu^(2+) ions in order of their tendency to be liberated at cathode. [E_(cu^(2+)|Cu)^(@)=+0.34V, E_(2H^(+)|H_(2))^(@)=0.00V , E_(Zn^(2+)|Zn)^(@)=-0.76V E_(K^(+)|K)^(@)=-2.93V]

Heating a mixture of Cu_(2)O and Cu_(2)S gives -
