Question

What is the total concentration of all ions (the sum of their individual concentrations) in aqueous solutions of the following?

Hint: Each substance is an electrolyte that dissociates in water to produce ions. Use the link table of polyatomic ions if you do not recognize the polyatomic ion. For example, Na2SO4 -> 2Na1+ + SO42- when it dissolves, so a 1 M soln of Na2SO4 is 2M in Na1+ and 1M in SO42- and the total concentration of ions is 2 M + 1 M = 3M.

Explanation / Answer

NaCl -> Na+ and Cl-

Therefore we have twice concentration...

[Na+] = 0.084

[Cl-] = 0.084

Total Concentration is addition = 2x0.084 = 0.168

For Na3PO4

Na3PO4-> 3
