  1. I'm assuming this is meant to be a buffer problem.
    .............H2CO3 + KOH ==> KHCO3 + H2O
    I..............0.1 mol....0...................0............0
    add........................0.04.........................
    C............-0.04.......-0.04..........+0.04
    E..............0.06..............0...............0.04
    Plug the E line into the Henderson-Hasselbalch equation
    Post your work if you get stuck.
