Question

which water is the most alkaline? rain, river, or distilled water?

Answer 1

Among rainwater, river water, and distilled water, distilled water is typically the most neutral, with a pH around 7. Rainwater can have a slightly acidic pH due to dissolved carbon dioxide and other atmospheric pollutants, often around 5.5 to 6.5. River water can vary widely depending on its source, surrounding environment, and presence of minerals and organic matter, but it can also range from slightly acidic to slightly alkaline.

In general, if you're considering alkalinity in terms of higher pH (above 7), then river water could potentially be more alkaline than both rainwater and distilled water, depending on the specific water chemistry. However, neither distilled water nor rainwater is typically alkaline. The alkalinity of river water can be influenced by factors such as geological features, vegetation, and human activity.
