2024年5月21日 · H2Se is a stronger acid than H2S. The bond energy of H2Se is less than H2S, making it easier for the hydrogen atom to leave the molecule. Therefore, H2Se is expected to be a stronger acid than H2S.

2019年1月5日 · Similarly, pure 100% dry $\ce{H2S}$ is theoretically a stronger acid than perfectly dry gaseous $\ce{HCl}$ due to a smaller bond dissociation energy and weaker dipole interaction. But, when it comes to aqueous medium, many factors are taken into account to decide the strength of acidity.

2024年12月20日 · Why h2s is acidic and h2o is neutral? H2S is acidic because when dissolved in water, it forms hydrosulfuric acid (H2S + H2O → H3O+ + HS-). The hydrogen sulfide molecule can donate a proton to ...

2024年5月23日 · H2S (aq) (H2SO4 is sulfuric acid). The acids with "hydro" at the start of their names are all derived from dissolved gases, e.g. hydrochloric acid is aqueous hydrogen chloride, hydrocyanic acid is ...

2024年5月28日 · Why h2s is acidic and h2o is neutral? H2S is acidic because when dissolved in water, it forms hydrosulfuric acid (H2S + H2O → H3O+ + HS-). The hydrogen sulfide molecule can donate a proton to ...

Compare the following: Acid 1: hydrosulfuric acid, H2S Acid 2: dihydrogen phosphate ion , H2PO4 Acid 3: nitrous acid , HNO2 What is the formula for the strongest acid ? Submit Answer Retry Entire Group 3 more group attempts remain Compare the conjugate bases of these three acids. Acid 1: hydrosulfuric acid, HS Acid 2: hydrocyanic acid , HCN Acid 3:

2019年11月10日 · I should prove (show) the acid nature of $\ce{H2S}$ by writing two chemical interactions. I am really sorry if the terms I am using aren't the right ones. It's the first time I've ever used this part of the language. Which reactions should I write, and why? I think the first one must be neutralization: $$\ce{H2S + 2 NaOH -> Na2S + 2 H2O}$$
