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.
Please answer all parts!
0.0540-M NaCl _______ M 0.0820-M Na2SO4 _______ M 0.0220-M K2Cr2O7 ______ MExplanation / Answer
0.0540M NaCl ------> Na+(0.0540) + Cl- (0.0540)
total concentration of ions in NaCl =0.0540+0.0540= 0.108M
2. 0.0820 Na2SO4 -> 2Na+ (2*0.0820M )+ SO4-2 (0.0820)=0.246M
3. 0.0220M K2Cr2O7 ------->2K+ (2*0.0220) + Cr2O7-2 (0.0220) = 0.066M is the total concentration of ions
