Using a pipette, add the remaining few drops to avoid an extra addition of distilled water to the mark above the neck of the measuring cylinder. In these cases, you seem to be breaking the same oxygen-hydrogen bond each time, and so you might expect the strengths to be similar. As an adjective acid is sour, sharp, or biting to the taste; tart; having the taste of vinegar. As nouns the difference between acid and basicity is that acid is a sour substance while basicity is (uncountable) the condition of being basic. ACIDITY. Give examples.
