實驗背景:
電極:兩根鐵棒
電壓:8V(時間關係.....1.6V就可以電解)
水溶液:自來水+食鹽

為呈現最真實的狀況 影片絕無剪接(因為麻煩 XD)

原理說明:
一.陽極的反應:1.鐵棒因為失去電子(e-) 而變成鐵離子(Fe3+, 黃色) 而使得溶液變黃 2. 水解離出氫離子(H+) 3.食鹽(氯化鈉)解離出鈉離子 (Na+) 4.氧離子還原成氧氣 5.氯離子還原成氯氣
二.陰極的反應:1. 水解離出氧離子(O 2-) 2.食鹽(氯化鈉)解離出氯離子 (Cl-) 3.鐵離子氧化成金屬鐵 或跟氧離子結合成氧化鐵(黃褐色浮游物質)

補充說明
1.兩根電極會因為距離減少而增快反應速率
2.治療時的電壓跳動(E=1.6~2.1V) 來自電極表面的雜質(氧化鐵)附著 或導電度低(食鹽加太少)
