Question

Name 11.) Write the acid ionization constant expression for the ionization of the hydrogen sulfate ion, HSO4, in aqueous solution. H,SO, 1H,0 HSO;] a.Ka = HSO H,0 HSO:1 12.) Consider the reaction NH4Cl(s) = NH3(g) + HCl(g) If the pressure is decreased on an equilibrium mixture of these three substances equilibrium will 'because . a. shift to the right; lower pressure favors fewer moles of gas b. shift to the right; lower pressure favors more moles of gas c. shift to the left; lower pressure favors fewer moles of gas d. shift to the left, lower pressure favors more moles of gas e. be unchanged; solid NH4CI does not appear in the equilibrium constant expression.

Explanation / Answer

11. Reaction of ionization of HSO4-

HSO4-(aq) +  H2O(l) <---> SO42-(aq)+ H3O+(l)

Ka = [SO42-][H3O+]/[HSO4-]

Option A.
