Question

Does the equilibrium lie to the left or the right? Explain why (what makes the acid or base weaker or stronger)

sulfurous acid (aq) + flouride ion (aq) <-> hydrogen flouride (aq) + hydrogen sulfite (aq)

bisulfide (aq) + hydrogen cyanide (aq) <-> cyanide ion (aq) + hydrogen sulfide (aq)

Answer 1

Ang = Reaction 1 Hy sou (aq) + pe caquous) - HF (aq) + H Sot Stoong acid Equlibrium lie to the right side because H₂ Soy is a Strong acid and can easily loss tt-long. H₂ soy is strong acid because it gives a stable and weak conjucate base isou ion. Reaction 2 82-199) + HCN caq) = a (aq) + Has (aq) 1 weak and Eaulibrium q this reaction lie to the left because HCN is a weak auid and it will not Htions easily to form CNT and Haso HON CN is weak is not and the because so stable. its Conjucate base is
