The ph scales
WebbAcid Rain and the pH Scale. The pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic. Webb10 apr. 2024 · on 10 April 2024.
