    I have 2,5mL with concentration 0,1 mol/L and 7,5mL with concentration 1 mol/L.
    When i put them together this will form a complex ion: .

    How can i now determine the concentration of ?

    (This is for my preparations for an experiment tomorrow)

    I have found out that i used to do these kind of exercices in class in highschool, but i forgot most of it :?
    Beginning: [] = 0.1 mol/L , [] = 1 mol/L, [] = 0 mol/L
    Now i have to do the experiment to find out the equilibrum so i can determine the and complete the rest of the table.
    It's slowly returning bit by bit

    Unless there is a major flaw in my logic here, this can be closed.
