pH at maximum concentration of a certain species (Phosphoric acid)

The fraction of the dyhydrogenphosphate, while ignoring the third ionization, is: $$x(\ce{H2PO4-})=\dfrac{K_\text{a1}\cdot [\ce{H+}]}{[\ce{H+}]^2+K_\text{a1}.[\ce{H+}] + K_\text{a1} \cdot K_\text{a2}}\...

Frequency to induce nitrogen inversion

The inversion frequency depends on the vibrational energy level, and the shape of the potential which has the form of a double well with a 'hill' in between The lowest transition has a gap of $0.7935\,...

pH at maximum concentration of a certain species (Phosphoric acid)

What people find intuitive depends on their experience, and what proofs they can follow depends on their mathematical background. Thus, this might not add anything to Poutnik's or AChem's answer. ...
