CHEMICAL EQUILIBRIUM: SMART WORKSHEET PART I. EQUILIBRIA OF COMPLEX IONS The following series of questions pertains to Part I of the Chemical Equilibrium Experiment, where you consider the equilibria of complexions. You considered the equilibrium below and compared the color of the solutions in four test tubes. \[ \mathrm{Fe}^{3+}(\mathrm{aq})+\mathrm{SCN}^{-}(\mathrm{aq}) \rightleftharpoons \mathrm{Fe}(\mathrm{SCN})^{2+}(\mathrm{aq}) \] PART I. 1 In the first tube, you added \( 0.5 \mathrm{~mL} \) of \( 0.2 \mathrm{M} \mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3} \). The solution , indicating that the equilibrium PART I. 2 To explain the observation in terms of Le Chatelier's Principle: The addition \( \mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3} \) 2 To reduce the stress caused by the 2 and re-establish equilibrium of the system, the equilibrium 2 , \( \left[\mathrm{Fe}^{3+}\right] \) \( \left[\mathrm{SCN}^{-}\right] \), \( 2 \quad\left[\mathrm{Fe}(\mathrm{SCN})^{2+}\right] \) In the second tube, you added \( 1.0 \mathrm{~mL} \) of \( 0.1 \mathrm{M} \mathrm{KSCN} \). The solution , indicating that the equilibrium PART I. 4 To explain the observation in terms of Le Chatelier's Principle: The addition of KSCN (2). To reduce the stress of the 2 and re-establish equilibrium of the system, the equilibrium PART I. 5 In the third tube, you added \( 6 \mathrm{M} \mathrm{NaOH} \) dropwise. The formation of a precipitate occurs and the solution (2) indicating that the equilibrium PART I. 6 To explain the observation in terms of Le Chatelier's Principle: The precipitation reaction In the third tube, you added \( 6 \mathrm{M} \mathrm{NaOH} \) dropwise. The formation of a precipitate occurs and the solution 2 , indicating that the equilibrium 2 PART I. 6 To explain the observation in terms of Le Chatelier's Principle: The precipitation reaction To reduce the stress of the \( {\left[\overline{\left.\mathrm{Fe}(\mathrm{SCN})^{2+}\right] .}\right.} \)
