प्रश्न

Use the data given in below find out which of the following is the strongest oxidising agent.

`"E"_("Cr"_2"O"_7^(2-)//"Cr"^(3+))^⊖`= 1.33 V `"E"_("Cl"_2//"Cl"^-)^⊖` = 1.36 V

`"E"_("MnO"_4^-//"Mn"^(2+))^⊖` = 1.51 V `"E"_("Cr"^(3+)//"Cr")^⊖` = - 0.74 V

पर्याय

  • Cl 

  • Mn2+ 

  • `"MNO"_4^-`

  • Cr3+ 

MCQ

उत्तर

`"MNO"_4^-`

Explanation:

The higher the positive value of standard reduction potential of metal ion, the higher will be its oxidizing capacity.

Since, `"E"_("MnO"_4^-//"Mn"^(2+))^⊖` has value equal to 1.51 V hence it is the strongest oxidizing agent.

Which cell will measure standard electrode potential of copper electrode?


The positive value of the standard electrode potential of Cu2+/Cu indicates that:

(i) this redox couple is a stronger reducing agent than the H+/H2 couple.

(ii) this redox couple is a stronger oxidising agent than H+/H2 .

(iii) Cu can displace H2 from acid.

(iv) Cu cannot displace H2 from acid.


Which reference electrode is used to measure the electrode potential of other electrodes?


Assertion: Cu is less reactive than hydrogen.

Reason: `E_((Cu^(2+))/(Cu))^Θ` is negative.
