WebMar 22, 2024 · Explanation: We use the pH equation, which states that, pH = −log[H +] [H +] is the hydrogen ion concentration in terms of molarity (M) or mol/L. So here, we have, [H +] = 0.075 M, since the substance we are dealing with is an acid. And so, the pH will be, pH = −log[0.075] ≈ 1.12. WebPerchloric Acid 0.1 mol/l (0.1N) in acetic acid (Reag.
