What is the pH level of Ammonia?

Ammonia, specifically in its aqueous form, is a weak base and has a higher pH level compared to neutral substances. When dissolved in water, ammonia partially ionizes to form ammonium ions and hydroxide ions, which is what causes the solution's basicity. The pH level of a standard aqueous ammonia solution typically lies around 11.6, indicating that it is considerably alkaline. This property is significant in various applications, such as in cleaning products and fertilizers, where its basicity plays a role in chemical reactions and facilitating processes.

In contrast, the other values listed represent pH levels typically associated with acidic or neutral solutions. The lower pH levels indicate the presence of acids or neutral substances, while ammonia's inherent property as a weak base leads to its substantial pH level, emphasizing its alkaline nature.
