Chemical Reactions (Part One)
... For example, peeled apples turn brown when exposed to the air because they react with oxygen in the air. Knowing what causes this reaction can help to slow it down. Placing sliced apples in water prevents browning because the apples are no longer exposed to air. The chemical ascorbic acid (vitamin C ...
