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.
