Write the balanced net ionic equation for the reaction of aqueous iron(l) ion reacting with H2G in acidic medium 9 Fe (a4) Without added acid, the H202 will form either OHT or O2, depending upon whether the H202 is reacting as an oxidizer or a reducer. If hydroxide ion is formed, the OH may react with some of the Fe to produce an insoluble hydroxide. Will the percent yield...

To add more information this was given to me for a lab that used
a weak acid and we added a strong base through titration. We just
observed how the ph changes. Later we then used a buffer with a
weak acid to see how buffers affect ph change. These questions are
basically surrounded around those topics to help us prepare.
However, I'm kinda confused about answering them because weak...
