Henry's Law strictly fails and is mathematically inapplicable when a gas is dissolved in a solvent u — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Henry's law assumes ideal behavior where the gas merely disperses physically. If the gas chemically reacts with the solvent (like $NH_3$ forming $NH_4OH$ in water) or dissociates into ions, the $p = K_H \chi$ relationship breaks down entirely.
