Fe(s) + 3AgNO3 ---> Fe(NO3)3 + Ag(s)
The oxidation # of Ag on the left is 1+ and on the right it is zero. It has gained electrons and has been reduced.
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
Mn (maganese)
Silver (Ag)
yes as zinc is oxidised and hydrogen is reduced
Your reaction is AgNO3 + Na ==> NaNO3 + AgIn this reaction Ag goes from 1+ to zero, so it has been reduced. Na goes from zero to 1+ so it has been oxidized.
Ag+
Iron reduce silver cations.
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
Sodium (Na) has been reduced.
Mn (maganese)
Silver (Ag)
Silver (Ag)
yes as zinc is oxidised and hydrogen is reduced
It is a REDOX reaction. Sodium is oxidized by Fluorine which is itself reduced by the sodium. 2Na + F2 = 2NaF.
Your reaction is AgNO3 + Na ==> NaNO3 + AgIn this reaction Ag goes from 1+ to zero, so it has been reduced. Na goes from zero to 1+ so it has been oxidized.
Cu is being reduced and Zn is being oxidized, hence Zn + CuSO4 --> ZnSO4 + Cu
The oxidation number of zinc (Zn) in Zn(NO3)2 is +2, while in Zn(OH)4^2-, it is also +2. Therefore, there is no change in the oxidation number of zinc.
