How do you calculate concentration of ions in a solution ...

Jan 25, 2015  The concentration of ions in solution depends on the mole ratio between the dissolved substance and the cations and anions it forms in solution. So, if you have a compound that dissociates into cations and anions, the minimum concentration of each of those two products will be equal to the concentration of the original compound. Here's how that works: NaCl_((aq)) -> Na_((aq))^(+) +
