Which substance is the most acidic? sodium hydroxide tomato juice lemon juice water

The correct answer is C. Lemon juice

Explanation:

The acidity of a solution depends mainly on their ph, in this way a pH from 0 to 6 indicates a substance is acid, a pH of 7 shows the substance is neutral and a higher pH shows a substance is a base which is the opposite to acids as bases accept hydrogen ions if dissolved while acids release them. Also, the lower the pH the most acidic a solution is. In this way, lemon juice has a pH of 2 and therefore is the most acidic in comparison to tomato juice with a pH of 4, water with a pH of 7 (neutral pH) and sodium hydroxide with a pH of 12 (base).
