WebJan 30, 2024 · It can be used to calculate the concentration of hydrogen ions [H +] or hydronium ions [H 3 O +] in an aqueous solution. Solutions with low pH are the most acidic, and solutions with high pH are most basic. Definitions Although pH is formally defined in terms of activities, it is often estimated using free proton or hydronium concentration: WebStep 1: Use the pH value to find [H +] ion concentration by rearranging the pH formula. By knowing the concentration of [H+], we can also apply it to the concentration of A - since the reaction of weak acids is at equilibrium. H + = 10 − p H [ H +] = 10 − 5.3 = 5.0 ⋅ 10 − 6. Step 2: Make an ICE chart.
