Spectrophotometric Determination of an Equilibrium Constant Introduction: In this experiment‚ you will study the reaction between aqueous iron (III) nitrate‚ Fe(NO3)3‚ and potassium thiocyanate‚ KSCN. They react to produce the blood-red complex [Fe(SCN)]2+. Fe3+ + SCN- ( [Fe(SCN)]2+ The equilibrium constant expression may be expressed as: K = [pic] You will prepare a series of standard solutions that contain known concentrations of [Fe(SCN)]2+ and will determine

Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

Assessing group work Advice and examples Introduction There is a great deal of benefit to be gained from group work‚ for both staff and student alike. From the lecturer’s point of view it can promote a variety of transferable skills and‚ depending on how the work is assessed‚ it is possible to enhance the learning process too. On a purely pragmatic level it may also be possible to save time spent on assessing students’ work. From the student point of view‚ engaging in group work offers a range

The first evidence of Charlie’s failure as a leader is when he calls the group together to communicate the news about losing their major customer. The mood is somber as Charlie calls the group together to “mourn” (Sloane‚ The Chattanooga Ice Cream Division‚ HBR‚ p.1) and to figure out what needs to be done about it. As a leader he must exude a sense of “positive energy” (Jack Welch‚ Winning‚ p.84) to prepare his people to act and energize their best thinking to deal with this challenge. His style
