PLEASE HELP :-)
calculate the buffer ph of CH3COOH/CH3COO- buffer solution with an equal molar concentration of CH3 COOH and CH3COO-. given the ionization constant of acetic acid, Ka is 1.73 ' 10-5
We can solve this problem using the long hand solution, wherein we 1 by 1 analyze the different equilibrium reactions or by simply using the Henderson Hasselbach equation. The equation is
pH = -log(pKa) + log (salt/acid)
since the acid and the salt have the same concentration, the log (salt/acid) term is equal to zero.
