In the laboratory you dissolve 23.7g of barium chloride in a volumetric flask and add water to a total volume of 500ml.
What is the molarity of the solution?M
What is the concentration of the barium cation?M
What is the concentration of the chloride anion?M

Answer 1

Molecular weight of Bacle = 208.23 g/mol 208·32 g Bactz in lodo mL of water = 1 (0Bacle - Solution 1000 ml of water = 20813 Bach solution 208.3 Now, 23:7 g of Back in loome of water = 23.7 (M) of - Bach Sulaty .: 23.79 of Bally in '500 ml of water = 23.7x1000 208.3 0.2275 (M) 2m As Bally completely dissociates in water, as Badly = Ba2+ +241" So, the concentration. Ba2t will be some as Back concentration & Concentration of a wiube the twice the concentration of the Back Solution of 1 mol Back dissociates to form 2 molis of a fon. So, con centration of Concentration of concentration of Solution = 0.2275(M) Ba 2+ = 0.2275*1 = 0.2275) CO = 2 x 0.2275 -0.455 (m)
