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

2024年6月1日 · HSO4 is Hydrogen Sulphate and an amphiprotic species. It is the conjugate base of H2SO4. H2SO4 is sulphuric acid, a very strong acid. ... acid (weak), because pka is near 7.

2024年5月29日 · It depends on the concentration. pH is the negative log of the concentration of H+ atoms in a solution (measured it molarity, mol/L). Phosphoric acid (H3PO4) has 3 Hs in it, so for every molecule ...

2025年1月19日 · 1-pKa of HClO4 is 10 and pka of H2SO4 IS 1.9. ... HSO4 is a weaker acid than H2SO4 because the presence of the additional hydrogen atom in H2SO4 makes it more likely to donate a proton, resulting ...

2024年5月27日 · What is the pH of Nahso4? The pH of a solution of NaHSO4 would depend on its concentration. However, for a dilute solution, NaHSO4 would be slightly acidic with a pH below 7 due to the presence of ...

Sodium hydrogensulfate contains the HSO4- ion therfore it can function as an acid. It's pKa value is 1.9.

2024年5月31日 · HSO4- is a weak acid. It is the conjugate base of sulfuric acid (H2SO4), which is a strong acid. However, HSO4- itself is a weak acid and partially dissociates in water.

2024年5月22日 · HSO4- is a weak acid. It is the conjugate base of sulfuric acid (H2SO4), which is a strong acid. However, HSO4- itself is a weak acid and partially dissociates in water.

2024年5月24日 · The oxidation number of sulfur in the bisulfate ion (HSO4-) is +6. Sulfur typically has an oxidation number of -2 in sulfates (SO4 2-) and gains an additional oxygen atom in bisulfate, hence the ...

2024年5月28日 · In bisulfate ion (HSO4-), the overall charge is -1, so the oxidation number of sulfur can be calculated as -1, taking into account the oxidation number of sodium as +1.
