The Ka of bromoacetic acid is 2.00 ×10–3. What masses of bromoacetic acid (CH2BrCOOH) and sodium bromoacetate (CH2BrCOONa) are needed to prepare 1.00 L of pH = 2.100 buffer if the total concentration of the two components is 0.200 M? g of bromoacetic acid g of sodium bromoacetate. P.S the answer is not :Mass of CH2BrCOOH = moles / Mol.wt = 0.1598 / 138.94 = 0.001150 g Mass of CH2BrCOONa = moles / Mol.wt = 0.04402 / 160.9 = 0.000273 g
