Suppose you have a buffer at pH 5.0 that is 1.00 M in HX and 1.00 M in X- , where HX is a weak acid with Ka =1.0 x 10^(-5) M. Calculate the effects of adding 50 ml of 1.0 M HCl to a 1-liter portion of this buffer and of adding 50 ml of 1.0 M NaOH to a separate 1-liter portion. What will the final pH be in each case?
