Determine the capacity of this buffer solution for resisting pH change when acid is added. Assume the volume does not change
Problem- Which reagent can affect the following transformation? I think a and b can do the same thing although I'm not sure why one nitro group reduces down to nh2 and not both nitro groups in the transformation.
