Apples turn brown when exposed to oxygen, a process called enzymatic browning. Liquids that contain acids, such as lemon juice or vinegar, can help slow this browning process by lowering the pH and inhibiting the activity of the enzyme polyphenol oxidase. Other liquids, like water or soda, don't prevent browning effectively, but can still cause oxidation if they allow oxygen to reach the apple's surface.
