How to calculate the pH of 0.120 M of HClO2? plssss i need the answer asap.

  • CHEMISTRY -

    ........HClO2 + H2O ==> H3O^+ + ClO2^-
    I.....0.120..............0.......0
    C........-x..............x.......x
    E.....0.120-x............x.......x

    Substitute the E line into the Ka expression for HClO2 and solve for x = (H^+), then convert to pH = -log(H^+)
