MasteringChemistry: H... <Homework 5 + lon Concentration 5 of 24 Review I Constants I Periodic Table 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 Al+ and 3 M in Cl.1 M of (NH4)2 SO4 is 2 M in NH,+ and 1 M in SO42-. Part A What is the concentration of K in 0.15 M of K2S? Express your answer to one decimal place and include the appropriate units. • View Available Hint(s) Value Units Submit Part B If CaCl2 is dissolved in water, what can be said about the concentration of the Ca2+ ion? • View Available Hint(s) It has the same concentration as the Cl- ion. Its concentration is half that of the Cl- ion. Its concentration is twice that of the Cl- ion. Its concentration is one-third that of the Ci- ion. 341503 6. étv FEB 23 MacBook Pro

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.
