Which is a common household item related to acids and bases?

• A. Stomach acid, antacids, and household cleaners.
• B. Water and coffee.
• C. Glass and mirror cleaners.
• D. Soaps and lotions.

Answer: (A)

Acids and bases show up in everyday items around the home, and you can see how they work through everyday examples. Stomach acid is an actual acid inside the body. Antacids are bases used to neutralize that acid, showing how bases counteract acids. Household cleaners are designed with either acidic or basic formulas to tackle grime and minerals, illustrating practical uses of both types of substances. This mix demonstrates acids, bases, and neutralization in common tasks, making it the best example of items related to acids and bases.

The other options don’t show the link as clearly. Water is essentially neutral, and coffee is acidic but not a household category focused on acids and bases. Glass and mirror cleaners can be either acidic or basic but don’t collectively emphasize the acid–base relationship. Soaps and lotions aren’t primarily about acids or bases in everyday use.
