Sagot :
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
