Which of the following best defines an acidic solution? A. A solution with a pH less than 7 B. A solution with a pH equal to 7 C. A solution with a pH greater than 7 D. A solution with a pH less than 0

An acidic solution is defined as a solution with a pH less than 7, meaning it has a higher concentration of hydrogen ions than pure water. These solutions can range from mildly acidic (like a lemon juice around pH 2) to strongly acidic (like battery acid, which can have a pH near 0). Understanding acidic solutions is essential in various fields, from chemistry labs analyzing chemical reactions to the culinary world where the balance of acidity can elevate flavors. For example, in cooking, adding vinegar (which is acidic) can enhance the taste of a dish, demonstrating the practical significance of pH levels in everyday life.
