On the flip side, a 0.0005 M HCl solution is dilute, yet still strong. Conjugate acid is an acid that formed when the parent base compound gains one proton and the conjugate base is a base that formed when the parent acid compound loses one proton. Is NO2 a weak conjugate base? Expert...
Your graphs, which will be used as a template for your lab data, should look like:28 When you titrate a weak acid with a strong base, such as NaOH, the reaction will go essentially to completion, giving an acidic solution until the equivalence point OH– + HC2H3O2 C2H3O2–+ H2O(1) ...

Consider the titration of a weak acid with a strong base. Determine the pH at the equivalence point when 10.0 mL of 1.55 M HC2H3O2 is titrated with 1.25 M NaOH. Ka(HC2H3O2) = 1.8 x 10-5; Kw(H2O) = 1.0 Consider the titration...
base for the buffer. The buffer equilibrium is HC2H3O2 H + + C2H3O2 – acetic acid acetate ion For acetic acid, Ka(HC2H3O2) = 1.8 x 10 -5 so pKa = -log10Ka = 4.74. Thus when [HC2H3O2] = [C2H3O2 – ], pH = pKa = 4.74. 1 2 Basic Buffers In a basic buffer both the ...
