Which of the following lists describes characteristics of an acid?
Bitter taste, high pH , and caustic
Sour taste, low pH , and dissolves metals
Sour taste, high pH , and dissolves metals
Slippery, low pH , and caustic

Sour taste, low pH, and dissolves metals are the characteristics that describe an acid. Acids have a distinct sour flavor, making them easily identifiable in foods like citrus fruits. Their low pH value, usually below 7, signifies that they are on the acidic side of the pH scale, which allows them to react with metals and cause corrosion.

Everyday examples abound where acids play an important role! For instance, hydrochloric acid is found in our stomachs to help digest food. Additionally, citric acid in lemons is a natural preservative and can even serve as a cleaning agent when mixed with vinegar. So, from your kitchen to your chemistry set, acids are definitely a part of our everyday lives!
