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. 0.0740-M NaCl ____ M 0.0200-M Na3PO4 ____M 0.0860-M K2Cr2O7 ____ M

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.
0.0740-M NaCl ____ M
0.0200-M Na3PO4 ____M
0.0860-M K2Cr2O7 ____ M
