Mn^+2 (ag) + C2O4^-2 (ag) <----> MnC2O4 (aq) K1= 7.9 x 10^3 MnC2O4(aq) + C2O4 (aq)...

Mn^+2 (ag) + C2O4^-2 (ag) <----> MnC2O4 (aq) K1= 7.9 x 10^3

MnC2O4(aq) + C2O4 (aq) <------> Mn(C2O4)2 ^-2 K2= 7.9 x 10^1

Calculate the value for the overall formation constant for Mn(C2O4)2^-2

K= [Mn(C2O4)2^-2]

         ------------------

      [Mn^2+] [C2O4^-2]^2

Please be very detailed and do not skip over any of the math. Thank you!

Answer #1

Answer:

Given the following data:

Mn2+    (aq)       + C2O42-    (aq)       <=>         MnC2O4   (aq)              K1 = 7.9 x 103

MnC2O4   (aq)    + C2O42-    (aq)    <=>        Mn(C2O4)22-   (aq)        K2 = 7.9 x 101

Calculate the value for the overall formation constant for Mn(C2O4)22-(aq):

Kf   =    [Mn(C2O4)22-]   /   [Mn2+][C2O42-]2

We can calculate the value of overall fromation constant for  Mn(C2O4)22-(aq):

(7.9 x 10^3)(7.9 x 10^1) = 624100

ANswer is 624100
