Sulfurous acid (United Kingdom spelling: sulphurous acid, also known as sulfuric(IV) acid, sulphuric(IV) acid (UK), thionic acid (since it has a thionyl group attached to 2 hydroxy groups)) is the chemical compound with the formula H2SO3. Raman spectra of solutions of sulfur dioxide in water show only signals due to the SO2 molecule and the bisulfite ion, HSO−3. The intensities of the signals are … Web16. H2SO3? That's not really a commonly used (or even stable) acid in solution. H2SO4, on the other hand, has two pKa values; one for the equilibrium of mono-deprotonation, the …

WebMar 13, 2024 · Plug your values into the Henderson-Hasselbalch equation, pH = pKa + log ( [A-]/ [HA]), where [A-] is the concentration of conjugate base and [HA] is the concentration of the conjugate acid. Keep in mind that since you've measured pH as a function of the titrant's volume, you need only know the ratio of conjugate base to acid.

WebSeveral sources provide pKa values for arsenic acid. Using a weight of evidence, the key value for the dissociation constant of arsenic acid on the different equilibrium in water was concluded using ATSDR (2007) report: H3AsO4 <-> H+ + H2AsO4- pKa 1 = 2.22 H2AsO4- <-> H+ + HAsO42- pKa 2 = 6.98 HAsO42- <-> H+ + AsO43- pKa 3 = 11.53 WebApr 12, 2024 · Its pKa value is 2.14. It donates its acidic hydrogen in an aqueous solution to form its conjugate base, H2PO4-. Is H3PO4 a strong or weak acid? It follows three sequential deprotonation steps to release all three acidic hydrogens but even after dissociation, split ions reform with each other and make Phosphoric acid again.
