Question

Several substances are labeled on the ph scale substance has the lowest [h ] concentration but is still considered an acid? a) Milk

b) Blood
c) Gastric fluid
d) Household lye

Answer 1

Milk has the lowest [H+] concentration but is still considered an acid.

Step-by-step explanation:

According to the pH scale, substances with lower pH values are considered more acidic. Based on the given pH values, the substance with the lowest [H+] concentration but still considered an acid is:

1. Milk, urine, saliva with a pH range of 6.3-6.6.

In this case, milk falls within the pH range of 6.3-6.6, which is lower than the pH values of blood (7.4), gastric fluid (typically below 2), and household lye (pH 13.5).
