Answer:
Oxygen
Explanation:
First, list out all the ions in the aqueous solution:
Ag+, NO3-
H+, OH-
In the anode, the substance lose electrons to undergo oxidation.
From the 4 ions, only OH- can lose electrons to form water and oxygen,
4OH- ---> O2 + 2H2O + 4e-
While others tend to gain electrons to form new substances instead (they undergo reduction).
Oxygen is the gas produced.
The gas should be treated as the Oxygen.
Identification of the gas:
here First, list out all the ions that should be in the aqueous solution:
Ag+, NO3-
H+, OH-
In the anode, the substance loses electrons for undergoing oxidation.
From the 4 ions, only OH- can lose electrons to form water and oxygen.
The balanced chemical equation be like
4OH- ---> O2 + 2H2O + 4e-
While on the other hand, it tend to gain electrons to create new substances. Therefore, Oxygen is the gas produced.
