Is tap water acidic or alkaline?

What is the pH of pure water?
7
The measurement of alkalinity and pH is needed to determine the corrosivity of the water. The pH of pure water (H20) is 7 at 25 °C, but when exposed to the carbon dioxide in the atmosphere this equilibrium results in a pH of approximately 5.2 because CO2 in the air dissolves in the water and forms carbonic acid.
