How many grams of acetic acid must be dissolved to produce 3875 ml with a Ph of 2.9?

  • Chemistry -

    pH = 2.9 = -log(H^+)
    Solve for (H^+) = 0.00126M
    ........HAc ==> H^+ + Ac^-
    E.......x..0.00126..0.00126
    Ka = (H^+)(Ac^-)/(HAc)
    Substitute and solve for (HAc).
    grams = mols x molar mass
    g/L x 3.875 L = g/3875 mL.
