Analogy
Electrolysis is like changing a recipe: the particles, amounts and conditions decide what product you can make.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
Electrolysis uses electricity to break down ionic compounds.
Positive ions move to the cathode and gain electrons.
Negative ions move to the anode and lose electrons.
