← ScienceWhich outcome occurs in saltwater when subjected to electrolysis?
A)Chlorine gas forms at the anode.✓
B)Sodium metal deposits on cathode.
C)Brine salinity will evenly decrease.
D)Water's inherent pH increases.
💡 Explanation
Electrolysis of saltwater causes chlorine gas release at the anode because oxidation draws chloride ions which form chlorine gas, via the electron transfer mechanism; therefore, chlorine evolves rather than oxygen, because chloride ions are preferentially oxidized in such solutions.
