The product of sodium oxalate (NaC2O4) and silver ions (Ag⁺) is silver oxalate (Ag2C2O4), which is a sparingly soluble compound. In solution, two silver ions can react with one oxalate ion to form the precipitate. Sodium ions (Na⁺) remain in the solution as spectator ions. Thus, the overall reaction can be represented as NaC2O4 + 2Ag⁺ → Ag2C2O4 (s) + 2Na⁺.

In the given redox reaction, silver nitrate (AgNO3) reacts with sodium nitrate (NaNO3) and elemental silver (Ag). The element that has been reduced is silver (Ag) because it is being converted from its ionic form (Ag^+) in AgNO3 to its elemental form (Ag). Reduction involves the gain of electrons, and in this case, Ag^+ gains an electron to become neutral Ag.
In the redox reaction between silver nitrate (AgNO3) and a reducing agent, silver (Ag) is oxidized. This occurs because silver loses electrons during the reaction, leading to its conversion from Ag+ in AgNO3 to elemental Ag. Thus, the element that has been oxidized in this reaction is the silver ion (Ag+).
Ag+
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.
Silver (Ag)
If Ag+ is converted to Ag, it has gained electrons. Ag+ indicates that silver has lost one electron, so when it is converted back to Ag, it means that electron has been gained back.
In the redox reaction, silver (Ag) has been reduced because it gains electrons in forming solid silver (Ag) from silver nitrate (AgNO3).
In the redox reaction AgNO3 + NaNO3 + Ag, silver (Ag) is reduced from Ag+ to Ag with the gain of one electron. Therefore, one electron is transferred in this reaction.

In the given redox reaction, silver nitrate (AgNO3) reacts with sodium nitrate (NaNO3) and elemental silver (Ag). The element that has been reduced is silver (Ag) because it is being converted from its ionic form (Ag^+) in AgNO3 to its elemental form (Ag). Reduction involves the gain of electrons, and in this case, Ag^+ gains an electron to become neutral Ag.
The product is silver sulfate, low soluble in water.
The compound with the formula Ag⁺ is silver ions, which have a charge of +1. Silver ions are formed when silver loses one electron.
In the redox reaction between silver nitrate (AgNO3) and a reducing agent, silver (Ag) is oxidized. This occurs because silver loses electrons during the reaction, leading to its conversion from Ag+ in AgNO3 to elemental Ag.
