Which of the following reasons correctly explains the color changes that take place when
8 mL of the 10% H2O2 is added to the solution of dichlorobis(ethylenediamine)cobalt(II)?
Four choices will be given.
An excess of H2O2 has been used in this step since cobalt(II) is oxidized in the presence
of the decomposing hydrogen peroxide. In the reduction half reaction of H2O2 in a basic
solution hydroxide ions are formed, 2e- + H2O2(aq) 2OH-(aq).
Which of the
following is the correct balanced ionic equation for the redox reaction occurring when the
hydrogen peroxide is added to dichlorobis(ethylenediamine)cobalt(II) solution? Three
choices will be given.
Which of the following is the correct balanced equation for the reaction that takes place
when concentrated hydrochloric acid is added to dichlorobis(ethylenediamine)cobalt(III)
hydroxide solution? Three choices will be given.
