It CdSo4 + H2S = CdS + H2so4

There are 0.1 milimoles of So4 Thereofere increase in H+ will be 0.2 millimoles

HCl is 0.08N therefore molarity of H is 0.08M

10 ml Therefore 0.0008Moles

Total H+ = 0.001moles

NOw in 100ml The concentration is 0.01 M Hence pH = 2

Virang your solution was of great help!!! But I would like to bring to your notice that you have made a grave mistake in the last step.

Before dilution volume is 10ml and concentration of H+ is .001 moles. So after solution to 100ml the H+ concentration will be. 0001 ...therefore the answer should be rather 4.
