Answer:Many common household products contain acids or bases, and you likely use them without consciously thinking about their chemical properties. Here's an example:Cleaning with vinegar (acid):When cleaning surfaces or removing mineral deposits, you might use vinegar, which is a dilute solution of acetic acid. You're utilizing its acidic properties to dissolve grime or hard water stains without necessarily thinking, "I'm using an acid to clean."Using baking soda (base):Baking soda (sodium bicarbonate) is a common base used in baking as a leavening agent or for odor absorption in refrigerators. When baking, you're using its basic properties to react with acidic ingredients and produce carbon dioxide, causing dough to rise, often without focusing on the acid-base reaction.
