Answer 1

Lemon juice, with a pH of 4, is considered an acid because it has a pH level lower than 7.

Step-by-step explanation:

The pH scale is used to classify substances as acidic, basic (alkaline), or neutral. A pH level lower than 7 indicates an acidic substance, a pH level higher than 7 indicates a basic substance, and a pH level of exactly 7 indicates a neutral substance. In this list of liquids, water has a pH of 7, which is neutral. Milk has a pH of 11 and hand soap has a pH of 12, both of which are considered basic. Lemon juice, with a pH of 4, is acidic and is the correct answer to the question.

Answer 2

Answer: C. Lemon Juice

Explanation: Lemon Juice (along with vinegar) is considered to be a very weak type of acid. It would have the highest pH level out of all the options. You feel a little tingle in your throat when you drink lemon juice right? Well that is because of its acid.
