Assertion: `Cu` is stronger reducing agent than `H^(+)`.
Reason: `E^(0)` of `Cu^(2+)//Cu` is negative.

Assertion(A) Cu is less reactive than hydrogen. Reason(R) E_(Cu^(2+)//Cu)^(o+) is negative.

Assertion (A) : Cu is less reactive than hydrogen. Reason (R) : E_(Cu^(2+)|Cu)^(@) is negative.

Assertion(A) Cu is less reactive than hydrogen. Reason(R) E_(Cu^(2+)//Cu)^(o+) is negative.

The positive value of the standard electrode potential of Cu^(2+)// Cu indicates that …………… 1) This redox couple is a strongest reducing agent than the H^(+)//H_(2) couple. 2) This redox couple is a stronger oxidising agent than H^(+)//H_(2) 3) Cu cannot displace H_(2) from acid. 4) Cu cannot displaced H_(2) from acid.

Assertion: Cu^(2+) is more stable than Cu^(+) Reason: Electrode potential is more important in determining stable oxidation state than electronic configuration.

Assertion (A): While the extraction of copper, one of the steps involved is Cu_(2)S+2Cu_(2)O to 6Cu+SO_(2) Reason (R): In this reaction Cu_(2)S is the reducing agent whereas Cu_(2)O is the oxidising agent.

Assertion: Cu^(2+) ions get reduced more easily than H^+ ions. Reason: Standard electrode potential of copper is 0.34 V.

Assertion: Cu^(2+) ions get reduced more easily than H^+ ions. Reason: Standard electrode potential of copper is 0.34 V.

Assertion: [Cu(CN)_4]^(2-) is more stable than [Cu(H_2O)_4]^(2+) Reason: On heating [Cu(H_2O)_4]^(2+) with NH_3, [Cu(NH_3)_4]^(2+) is formed.
