From the redox reaction Zn+ Ni^2+--> Zn^2+ Ni we can say that?

1/2 eqns:
Ni^2+ + 2e- --> Ni(s) E0: -0.24V
Zn^2+ + 2e- --> Zn(s) E0: -0.76V

the lowest reduction voltage gets reversed as its most readily oxidised (loss of electrons) ie Zn becomes oxidised
therefore,

Zn+ Ni^2+ --> Zn^2+ Ni .. E0: -0.24 -(-0.76) = 0.52V

in answer to your question, yes, it can be said.
ofcourse, under non-standard conditions, the nerst equ must be used.

    You can say that zinc is higher in the electromotive series, therefore more reactive, than nickel. Zinc metal will dissolve in this solution, and nickel ions will be deposited as metallic nickel.

    The zinc is much more reactive than the nickel.Also,the nickel is oxidised and the ainc is reduced.

    all the peeps who are saying something about 'more reactive' haven't taken chem in a while (neither is 'more' reactive than the other)

    one is oxidized, one is reduced, (nickel and zinc, respectively), one is an oxidizing agent, the other is a reducing agent (the reverse, respectively)

    that if this reaction is happening at standard conditions, it would be spontaneous, as E is positive

    that if this was set up in a lab as an electrochemical cell with all associated parts (salt bridge, etc), that the zinc would be going into solution while the Nickel would be accumulating in solid form - and by one convention, the zinc would be the anode (because that is where oxidation occurs) and the nickel the cathode, but by the convention of 'electron flow' those lables would be reversed

    the above reaction can b divided into
    i) Zn(s) - 2e- ---> Zn2+(aq) [E degree reduction = - .76V]
    ii) Ni2+(aq) + 2e- ---> Ni(s) [E degree reduction > - .76V]
    from the reactions v can say that Zn is more reactive than Ni. This is because Zn is oxidised in preference to Ni as reduction potential of Zn2+ is more negative than that of Ni2+. Since in a redox reaction , both oxidation & reduction occur , so Ni2+ is reduced as oxidation has already occured .

    Here you go pal:

    Zinc is a reducing agent as it has reduced nickel's oxidation state from +2 to 0. Ni^2+ is therefore the oxidizing agent

    zinc is oxidized n nikel is reduced..u can actually notice that the oxidation number of zinc increase from 0 to +2 and the oxidation number for nikel decreases from +2 to 0.
    hence, nikel is the oxidizing agent because it release 2 electrons to oxidize zinc while zinc is the reducing agent because it accepts 2 electrons frm nikel to reduce nikel

    This is a Redox reaction.
    Red - Ox
    Red - Reduction the gain of electrons
    Ox - Oxidation The loss of electrons.

    Zn loses two electrons to become Zn^2+ - so it is oxidised.
    Ni^2+ gains two electrons to become Ni - so it is reduced.

    The zinc gained two electrons, becoming unstable, while the nickel lost two, becming stable.

    Zn is oxidised because of an increase in oxidising # while Ni is reduced due to the decrease in oxidising #

    zn is acting as a reducing agent and nickel as an oxidizing agent.
    Zn gives out two ectrons to nickel and get oxidized. Ni accepts two electrons and get reduced. In a redox reaction, oxidizing agent get reduzed and reducing agent get oxidized.
