ROUND, PROBLEMS
Part B – Short answer questions Problem 1 Chemical crossword – inorganic chemistry (8 points) Letters A, B, D ect. stands for unknown inorganic compounds, which react as shown in table. Formulas for all organic compounds are known. •

Compound A contains transition metal and transition metal content is approximately 72% (by mass) Solutions of compounds U, N, Ģ are strongly basic. There are no information about solutions of other compounds. Solutions of compounds O and N colors gas flame yellow, while compounds U un Ō colors flame purple red. Water solutions of compounds V, P and L are blue. Substances E, G, H, M, R, S, Ā contain only one chemical element. Three transition metals are mentioned in this crossword. Equations in crossword are not balanced. Write chemical formulas for all compounds abbreviated with letters.

The first type electrode consists from metal (M(s)) and it’s ions in solution (Mx+(aq)). This time solution also contain protolytic pair from which conjugated base acts as ligands and form complex ions with Mx+. Draw graph to show how reduction standard potential is dependent on pH if free ligand concentration in solution is a) 0.1 M, b) 1.0 M and 5.0 M. Given electrode: Cu2+(aq) + 2e → Cu(s) Eo = + 0.345 V +
pKa(NH4+) = 9.25 Ligands: NH3 / NH4 Summary complex formation constants: lg β1 = 3.99 lg β1,2 = 7.33 lg β1,2,3 = 10.06 lg β1,2,3,4 = 12.03 lg β1,2,3,4,5 = 11.43 lg β1,2,3,4,5,6 = 8.9 Hints: 1. Assume that concentration sum for conjugate acid and base and acid are constant (if base are used for complex formation it is added to solution to maintain constant concentration or concentration of base is huge enough and stays almost constant). 2. Write mathematical equations for calculation real reduction standard potentials depending from molar fraction of metal ions in solution. Example: 3. Using MS Excel program calculate real standard potential values, if pH changes from 0 to 14 (step 0.5). Made calculation in three cases: a) conjugate acid and base concentration sum is CL = 0.1 M, b) CL = 1 M and c) CL = 5 M. All calculation results collect in table. www.biosan.lv FINAL
