What would a pH of 11 indicate about a solution?

A pH of 11 indicates that a solution is alkaline, which means it has a higher concentration of hydroxide ions compared to hydrogen ions. The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral. Values below 7 indicate acidity, while values above 7 indicate alkalinity. Therefore, a pH of 11 clearly falls into the alkaline category, suggesting that the solution has basic properties.

In the context of safety and chemistry, it's important to recognize that alkaline solutions can vary in their effects and applications. While they are not necessarily corrosive, some alkaline substances can be damaging to materials or tissues, depending on their concentration and other chemical properties. However, the defining characteristic of a pH of 11 is its classification as alkaline, which sets it apart from the acidic and neutral categories.
