Calculate the pH of 0.0115M acetic acid solution at 25 degrees celcius with Ka=1.75*10^-5

  • Chemistry - ,

    Note the correct spelling of celsius.
    CH3COOH lets call HAc.
    .............HAc ==> H^+ + Ac^-
    initial....0.0115.....0......0
    change.......-x.......x......x
    equil.....0.0115-x....x......x

    Ka = (H^+)(Ac^-)/(HAc)
    Substitute and solve for x then convert to pH.

    Thanx a lot GOD BLESS YOU
