Buffer -- Net Ionic Equations?
Consider an aqueous buffer solution made with near-equal amounts of hypochlorous acid and a hypochlorite ion salt. Write the complete, balanced, net ionic equations which show the direction of the reaction that takes place upon addition of a small amount of a strong base or a strong acid to the buffered solution.
Use only species chosen from those listed below:
HOCl OCl− H2O H3O+ OH−
a) OH− + _____ → _____ + OCl−
b) H3O+ + _____ → _____ + H2O
For a) I put OH- + HOCL -> H2O + OCl^- but I'm told it's wrong.
For b) I put H3O+ + OCL- -> HOCL + H2O but it's wrong, too.
Answer:
Looks fine to me... everything fits fine, and in each case, you're neutralizing the base/acid.
