Which of the following describes a liquid with a pH of 7?

A liquid with a pH of 7 is described as neutral. This means that it has a balance of hydrogen ions (H⁺) and hydroxide ions (OH⁻), resulting in no acidic or basic characteristics. Pure water, for example, is often used as a benchmark for neutrality because it has a pH of 7 at standard temperature and pressure.

In the pH scale, values below 7 indicate acidity, which means a higher concentration of hydrogen ions, while values above 7 indicate basicity (or alkalinity), which reflects a higher concentration of hydroxide ions. Therefore, a pH of 7 signifies that the substance is neither acidic nor basic, making it a neutral liquid.
