CHM 2046/Myers Worksheet 1 January 06, 2010 1. A Reaction Forming a “Complex Ion.” Fe +3 (aq) + SCN - (aq) Fe(SCN) +2 (aq) Without performing calculations, we want to determine which reactant is limiting. We shall “divide and test” to see which reactant, when added, will produce more product. Experimental Result : 2. Writing Equilibrium Constant Expressions. In general, for Reactants Products, For A + 2 B 3 C + 4 D, 3. The Units of Concentration used in K Expressions: State or Phase Symbol Property Type and Units Used Gases (g) Solutes in solution (aq) Solvent, other liquids (l) Solids (s) 4. Write out K expressions for each reaction. Use the proper term for each R and P. Fe +3 (aq) + SCN - (aq) Fe(SCN) +2 (aq) 2 ICl (g) I 2 (g) + Cl 2 (g) 2 ICl (g) I 2 (s) + Cl 2 (g) CaCO 3 (s) CaO (s) + CO 2 (g) Mg(OH) 2 (s) Mg +2 (aq) + 2 OH - (aq) 2 H 3 O + (aq) + Ag 2 S (s) 2 Ag + (aq) + H 2 S (g) + 2 H 2 O (l)
