The pH change for the given acidic buffer solution is 0.22.

HClO and ClO- is an acidic buffer, and with addition of HI, the concentration of acid increases while the concentration of salt decreases.

pH=pKa +log (salt/acid)

=7.54+log (0.326/0.369)

=7.54-0.05

=7.49

On adding Hydrogen iodide,

pH=pKa+ log((0.326-0.085)/(0.369+0.085))

=7.54+log (0.241/0.454)

=7.54-0.27

=7.27

Thus, the value of pH change cab be calculated as follows:

=7.27-7.49

=0.22
