Question

In order for the pH level of an acidic substance to be less than 2.25, the molar concentration of hydrogen ions, x, in the substance must satisfy the inequality –log x < 2.25. Review the table of values representing the left side of the inequality.
A 2-column table with 7 rows. Column 1 is labeled x with entries 0.01, 0.005623, 0.003162, 0.001778, 0.001, 0.0005623, 0.0003162. Column 2 is labeled negative log x with entries 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5.

What is the solution set for the molar concentration of hydrogen ions to have a pH less than 2.25?

(0, 0.005623)
(0.005623, ∞)
(0, 0.0005623)
(0.0005623, ∞)
