1. Determine the ionic strength of a 0.60 M solution of KSCN
2. By using the Debye-Huckel Equation, determine the activity coefficient of Zn+2 when the ionic strength is 0.0010 M.
3. Determine the activity coefficient of H+ in a solution which is having the 0.010 M HCL plus 0.040 M KClO4.What is the pH of the solution?
