- The formula for tartaric acid is preferably written as H2C4H4O6 rather than as C4H6O6. Explain why.In the reaction HSO4 (aq) + OH (aq) – so,2-(aq) + H20 (1), the conjugate acid- base pairs are HSO4 and So,2-; H20 and OH HSO4 and H30*; S04 2-and OH HSO4 and OH; so,2-and H20 HSO4 and H20; OHTand SO,2- HSO4 and OH; so,2-and H30*OH- + CH3COOH ==== CH3COO- + H2O.

- Type your answers in all of the blan When sulfurous acid, H,SOgis dissolved in water it.undergoes stepwise dissociation, initially giving up its first proton the in the reaction: H2SO3(aq) + H20(aq) = H30*(aq) + HSO, (aq) The resulting HSO, (aq) species is amphoteric in solution and can thus react with water as either an acid or as a base. The equilibrium expressions below show these 2 scenarios. Identify whether HSO, (ag) behaves as an acid or as a base in these reactions. HSO, (aq) + H20(1) H2SO3(aq) + OH (aq) In this reaction HSO, acts as alan HSO, (aq) + H,0(1) So, (aq) + H30 (aq) in this reaction HSO, acts as a an pe younenwerhare Fullscreen 9:28 PM a S2/2021 prt sc delete home 144 & 7. num lock backspace 6. 8. 7. 8.
