Suppose you have a buffer at pH 5.0 that is 1.00M 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 50ml 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?
