Read the Assertion and Reason below and choose the correct option. — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

The neutral pH depends on temperature (e.g., at 100°C neutral pH is ~6.14, making pH 6.8 basic), so Statement I is not universally true. However, $\sqrt{K_w}$ strictly defines the $[\text{H}^+]$ at neutrality for any given temperature, so $[\text{H}^+] > \sqrt{K_w}$ guarantees an acidic solution. Thus Statement I is incorrect but Statement II is correct.
