observation and conclusion for electrolysis and its application. pls answer
Answers
Answer:
Observations= The solution turns blue at the cathode (basic) and red at the anode (acidic). Twice as much gas is evolved at the cathode as at the anode. When the solutions in the two electrodes compartments are mixed, the indicator turns green (neutral).
Applications = Electroplating, Electroforming and Electrotyping
Metal Extraction (Electrometallurgy) Electrometallurgy is the process of electrolysis for extracting metal from the ore. ...

Electrocleaning.
Conclusion = The conclusion from these figures is that hydrogen should be produced at the cathode and oxygen at the anode from the electrolysis of water—which is at variance with the experimental observation that zinc metal is deposited and bromine is produced.
