Question

Quizplus · Accepted Answer

H₂S is the strongest acid among the given options because it is a hydride of a group 16 element (sulfur), and such hydrides tend to be more acidic than those of group 15 (NH₃, PH₃) and group 14 (CH₄). Additionally, H₂S is more acidic than H₂O due to sulfur's larger atomic size and lower electronegativity compared to oxygen, which makes the H-S bond weaker and more prone to releasing H⁺ ions.
