Explanation:
Detailed explanation-1: -pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
Detailed explanation-2: -A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm−3 has a pH of 0.
Detailed explanation-3: -Remember, a pH of 7.0 is neutral. Anything above that (7–14) is basic, and anything below that (0–6) is acidic. The pH of lemon juice is about 2.0, whereas tomato juice’s pH is about 4.0.
Detailed explanation-4: -Acidic cleaning agents have a PH level below 7, ranking from 0-6. These cleaners remove hard water build-up, mineral deposits, rust, corrosion, and grease. Examples of acidic cleaners include white distilled vinegar, toilet bowl cleaner, and citrus-based cleaning products.
