Chemistry

A solution is prepared that contains 10 mM NaCl, 20 mMCaCl₂, 20 mM BaCl₂, and 50 mMNiNO₃. Of course, all these salts completely dissolve totheir respective cations and anions. The pH is 7.0.
(a) Calculate the ionic strength of the solution.
(b) Calculate the activity coefficients for H⁺,Cl^-, and Ba²⁺ (use the Guntenbergapproximation because the solutions do, though note there are a fewother equations and a graph that can be used at your discretion anyother time).
(c) Compare the concentrations and the activities of these threespeciesâ€”what is the percent difference between the concentrationand the activity for H⁺, for Cl^-, and forBa²⁺?
