Crystal Field Theory: High Spin and Low-Spin Complexes
1 (a) Write a structural formula for two different isomers of [Co(H2O)2(en)2]Cl2. Indicate the oxidation state of the Co in each case.
(b) For the complexes in (a) above, draw a crystal field energy level diagram for either isomer, and indicate the electron distribution for (i) a high spin complex, and (ii) a low spin complex.
Would a solution of either isomer of [Co(H2O)2(en)2]Cl2 form a precipitate when mixed with a silver nitrate solution? Explain.
12.0 moles of gas are in a 8.00 L tank at 23.2 C. Calculate the difference in pressure between methane and an ideal gas under these conditions.
PH And Percent Ionization, 1. Determine the pH and the percent ionization in a 0.50M solution of KOBr. The Ka for HOBr = 2.5 x 10 ^ -9.
