Consider the following acid-base equilibrium:
H2S(aq) + H2O(l) <---> HS-(aq) + H3O+(aq)
(a) Identify the conjugate acid-base pairs in this equilibrium.

*see attached file for chart

The value of the equilibrium constant for the above reaction is 5.7 x 10^-8

(b) How will the concentration of H2S compare to the concentration of the HS- ion in any soluation in which this equilibrium occurs?
(c) The hydrogensulfide ion (HS-) produced in the equilibrium above can also react with water in an acid-base reaction. Write the equation for this reaction in the space below.
