in the reaction:Ni+SN4+-->Ni2+ (+)Sn2+ which species has been reduced?
1.Ni
2.Sn4+
3.Ni2+
4.Sn2+
i know its def Sn but im not sure which one.
In the given reaction, Ni+SN4+ --> Ni2+ (+) Sn2+, the species that has been reduced is the Sn4+ ion.
To determine which species has been reduced in the given reaction, you need to identify the change in the oxidation state (or oxidation number) of each species involved.
In the reaction: Ni + Sn4+ → Ni2+ + Sn2+
The oxidation state of nickel (Ni) changes from 0 to +2. This indicates that nickel has been oxidized and lost electrons.
On the other hand, the oxidation state of tin (Sn) changes from +4 to +2. This implies that tin has been reduced and gained electrons.
Therefore, in this reaction, the species Sn4+ has been reduced to Sn2+. So, the answer is:
4. Sn2+
