Question

rank the following from most acidic to least acidic. to rank items as equivalent, overlap them. ph = 14, ph = 3, ph = 5, h₃o⁺=10⁻⁶, h₃o⁺=10⁻². incorrect; try again; 4 attempts remaining. view available hint(s). previous answers submit

Explanation:

Step1: Recall pH - $[H_3O^+]$ relation

Lower pH or higher $[H_3O^+]$ means more acidic.

Step2: Calculate pH from $[H_3O^+]$

For $[H_3O^+]=10^{-6}$, pH = 6; for $[H_3O^+]=10^{-2}$, pH = 2.

Step3: Rank items

$[H_3O^+]=10^{-2}$ (pH = 2), pH = 3, pH = 5, $[H_3O^+]=10^{-6}$ (pH = 6), pH = 14.

Answer:

$[H_3O^+]=10^{-2}$, pH = 3, pH = 5, $[H_3O^+]=10^{-6}$, pH = 14
