Part a describe the electrodes in this nickel-copper galvanic cell. drag the appropriate items to their respective bins. view available hint(s) nickel copper standard reduction potentials for nickel(ii) and copper(ii) the standard reduction potential for a substance indicates how readily that substance gains electrons relative to other substances at standard conditions. the more positive the reduction potential, the more easily the substance gains electrons. consider the following: ni2+(aq)+2e−→ni(s),cu2+(aq)+2e−→cu( s), e∘red=−0.230 v e∘red=+0.337 v part b what is the standard potential, e∘cell, for this galvanic cell? use the given standard reduction potentials in your calculation as appropriate.

Part-A:

Anode is Nickel and Cathode is copper.

Part -B:

of the reaction is 0.567V.

Explanation:

Nickel-Copper cell electrodes are "Ni" and "Cu" rod.

Nickel electrode is dipped in solution.

Copper electrode dipped in solution.

Part -A:

Anode:

At anode oxidation takes place

Hence, anode is Nickel.

Cathode:

At cathode reduction takes place.

Hence, Cathode is copper.

Part-B:

Hence, of the reaction is 0.567V.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
