2014年3月23日 · Without giving a pKa table, this would be a bad question. I actually Googled the pKa2 of H2SO4 and its 1.99 (pKa1 = -10). I guess this is simply an exception where the …

2024年6月18日 · The pKa of HSO4- (the second pKa of H2SO4) is 1.92. The Ka is thus 0.0120

2016年2月7日 · Imagine if a different question had referenced H2SO4. Would we have plugged in pKa (H2SO4) + pKb (H2SO4) = pKw? Maybe, but it's much less likely, because we don't think …

2013年6月16日 · Which of the following relationships must be true? I. Pka1 (h3po4) is less than pka (HF) II. PKa2 (H3PO4) is less than pka2 (H2SO4) II. Pka (HF) is less than Pka1 (H2SO4) …

2011年10月5日 · The result numerically is that pKa2 of H2SO4 is less than pKa2 of H3PO4. Statement II is thus false." Why I'm confused: So, my understanding right now is that the lower …

2024年5月29日 · The increased strength of H2SO4 compared to HNO3 accounts for the fact that concentrated H2SO4 and HNO3 work together as a nitrating agent. ... Trifluoroacetic acid …

2024年5月27日 · How do you get the pH of Butanoic Acid in a 0.250 M solution with pka of 4.83? ... (H2SO4), which is a strong acid. However, HSO4- itself is a weak acid and partially …

2016年5月2日 · Yeah, basically. HCl aand H2SO4 you should know to be strong acids. So it's down to H3PO4 and HPO4 - since the pKa's of multi-protic acids increase as you lose more …

2024年5月28日 · Sodium hydrogensulfate contains the HSO4- ion therfore it can function as an acid. It's pKa value is 1.9.

2024年6月5日 · Yes, the pKa value for the reaction of CO2 plus H2O to form H2CO3 is approximately 6.35. This represents the equilibrium constant between the dissolved CO2 and …
