sel elektrolisis  menghasilkan perubahan kimia dengan tenaga lektrik.

Anode is named after whichever electrode that interacts with anion. That's why it is the positive electrode in electrolysis but the negative electrode in a chemical cell.

Ditto, cathode is named after whichever electrode that interacts with cation. That's why it is the negative electrode in electrolysis but the positive electrode in a chemical cell.

Dengan cara yang sama, katod dinamakan sempena mana-mana elektrod yang berinteraksi dengan kation. Sebab itulah katod ialah elektrod negatif dalam elektrolisis tetapi ialah elektrod positif dalam sel kimia.

tpok! terjemahan yg amat tepat!
