Due to the relatively high temperature of electrolysis, if sodium nitrate is present, it will decompose into sodium nitrite and oxygen at high temperatures, affecting the purity of chlorine gas
It will damage the membrane, and soon the current efficiency will decrease while the cell voltage will increase
The anode area will be acidic; due to the presence of nitrate ions, nitric acid and hydrochloric acid will be present as well. The combination of these acids results in a solution with extremely high corrosivity, and the anode will be corroded as a result.
