Detailed explanation-1: -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.
Detailed explanation-2: -As such, no substance (other than pure water or certain balanced solutions in water) have a pH of 7. Not even water has a pH of 7: only under certain conditions of temperature is the pH exactly 7.
Detailed explanation-3: -The pH of pure water is seven. Concentration of hydroxide ion and hydrogen ion is equal in pure water making it neutral.
Detailed explanation-4: -Answer and Explanation: If a substance has a pH that is greater than 7, it is alkaline.
