What is the general difference between tap water and mineral water?

• A. Tap water is generally soft water and mineral water is hard water
• B. Tap water is hard and mineral water is soft
• C. They are both soft
• D. Mineral water is carbonated only

Answer: (A)

The key idea is mineral content and source. Tap water comes from a city or well supply and is treated to remove impurities, which often leaves it softer with fewer minerals like calcium and magnesium. Mineral water comes from natural springs or deep underground sources and retains dissolved minerals, so it typically has higher mineral content and feels harder. Carbonation isn’t a defining feature of mineral water—it can be still or carbonated—so that option isn’t the basis for the distinction. In most everyday, restaurant contexts, the contrast described—tap water as soft and mineral water as hard—best captures the general difference.
