A stock solution containing Mn2 ions was prepared by dissolving 1.584 g pure manganese metal in nitric acid and diluting to a final volume of 1.000 L. The following solutions were then prepared by dilution: For solution A, 50.00 mL of stock solution was diluted to 1000.0 mL. For solution B, 10.00 mL of solution A was diluted to 250.0 mL. For solution C, 10.00 mL of solution B was diluted to 500.0 mL. Calculate the concentrations of the stock solution and solutions A, B, and C.
15.2 THE EQUILIBRIUM CONSTANT - Haber process: reaction; critical for the production of fertilizers & therefore to the food supply - the equil condition is reached from either direction - law of mass action: postulated; expresses, for any rxn, the relationship btwn the [ ] of the reactants and products present at equil aA + bB dD + eE - equil expression: [D] [E] e K c a b [A] [B] - equilibrium-constant expression ^ - equilibrium constant: K ; ncmerical value obtained when we substitute molar equil [ ]s into the equil constant expression - the equil-const expression depends only on t
