Familiarity information: ACIDIC used as an adjective is rare.Dictionary entry details.eing or containing an acid; of a solution having an excess of hydrogen atoms (having a pH of less than 7).
A pH number measures from 0 to14 how acidic or alkaline a liquid is -- anything above 7 is alkaline and anything below 7 is acid. Water has a pH level of 7 -- it's neutral, meaning it has the same amount of acids and alkalis, which balance each other out. When you're thinking about liquids in terms of their pH levels, going up or down one number on the scale represents a tenfold change in the acidity or alkaline nature of a liquid. For example, the pH level of milk is around 6. Because the pH level of water is 7, milk is 10 times more acidic than water. Vinegar has a pH of about 3, making it 40 times more acidic than water [source: Carpi].
