Step 1
Which statement describes what happens during electrolysis?
Answer
During electrolysis, ionic compounds undergo decomposition. When an electric current is passed through an ionic compound in a molten or aqueous state, the compound breaks down into its constituent ions. These ions move towards the electrodes, leading to the formation of different substances. Therefore, the correct statement is:
B ionic compounds are decomposed.
