When we report the concentration of a solution we are using the moles of the entire compound. For example, if we have a 2.00 M NiCl2 solution, that means that we have 2.00 moles of NiCl2 per liter of water. However, NiCl2 is a soluble ionic compound and in water it exists as separate Ni*2 and Cl- ions. In a given solution, we can determine the concentration of each ion present. For example, in a 2.00 M NICI2 solution, the concentration of Ni*2 ions is 2.00 M and the concentration of Cl- ions is 4.00 M. Therefore, the overall concentration of ions in a 2.00 M NiCl2 solution is 6.00 M ions. 23. Imagine you have a 2.0M Nacl solution. a. What is the concentration of Na* ions? b. What is the concentration of Cl- ions? c. What is the total ion concentration? 24. Imagine you have a 2.0M Na2SO4 solution. a. What is the concentration of Na* ions? b. What is the concentration of SO42 ions? c. What is the total ion concentration?
