Consider the following list of commonly found items and their pH values: 
Which of the choices includes all acids?

Quizplus · Accepted Answer

Vinegar, grapes, tomatoes, and coffee are all acidic with pH values below 7. Egg whites (pH 8) and baking soda (pH 9) are basic, while milk of magnesia (pH 10) is also basic but closer to neutral. Bleach (pH 13) is highly alkaline. Tomatoes (pH 4) are acidic but the presence of egg whites and baking soda in choice B makes it an incorrect option. Beer (pH 4) is acidic but butter (pH 7) and baking soda (pH 9) are not, so choice D is also incorrect.
