What is a characteristic of an alkaline solution?

An alkaline solution is characterized by having a pH greater than 7. In the pH scale, values below 7 indicate acidity, while a pH of 7 is neutral, such as pure water. Therefore, any pH value above 7 signifies that the solution is alkaline (or basic). This property is important in various fields, including chemistry, biology, and environmental science, as it affects chemical reactions, biological processes, and the behavior of substances in different environments. The notion of alkalinity is crucial, particularly in contexts such as soil health, maintaining aquatic ecosystems, or formulating certain cleaning products, where an alkaline environment can lead to specific desirable outcomes.
