Solution lon expected to hydrolyze Spectator ion(s) 0.1 M Naci 0.1 M Na2CO3 0.1 M NaC2H302...
lon concentration refers to the molar concentration of an ion in solution. It may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. For soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. For example, 1 M of AlCl3 is 1 M in A1 and 3 M in CI . 1 M...
