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

PPG INDUSTRIES: STATISTICAL QUALITY CONTROL INSTRUCTION PPG Cleveland was the largest automotive-coating manufacturing plant in the world with annual production exceeding 18 million gallons. The plant was a converter-type operation‚ which assembled and processed raw materials into hundreds of primers and topcoats for application at automotive assembly plants throughout the United States. When a sample of paint from the production process was received in the Cleveland quality-control lab

The concept of Rationality is defined as the ‘Preoccupation with calculating the most efficient means to achieve one’s goals’ (Bilton et al‚ 2002. Pg31) rather than ‘motivations derived from custom‚ tradition or emotion’ (Encyclopaedia‚ 2003). Rationalisation involves concepts such as logic‚ calculation and efficiency‚- fundamental aspects of Modernity as proposed by Max Weber. Weber believed that modernity involves ‘The rational application of Scientific method to all sectors

Determination of Chlorine and Iodine in Water I. Introduction The purpose of this laboratory was to determine the amount of chlorine and iodine in a sample of water by titration using a starch indicator and to standardize a sodium thiosulfate solution. Chlorine is added to municipal water supplies to purify it enough to become safe to drink. Iodine is also added to water when people camp or go hiking in the back country where they cannot bring purified water along. Chlorine and iodine are

CHM152LL LAB MANUAL COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS Complexometric Determination of Water Hardness Introduction Complex ions When a neutral molecule or anion (a Lewis base) donates electron pairs and attaches itself to a metal ion center (a Lewis acid)‚ the resulting cluster‚ or complex‚ of atoms becomes a single complex ion. When such complexes form‚ the electron donating groups (called ligands) form coordinate covalent bonds through empty orbitals on the metal ion. An example

Practical uses of statistical power in business research studies An important use of power is in the planning of sample sizes prior to gathering data used to evaluate statistical hypotheses. A number of business statistics texts illustrate this use of power (Anderson‚ Sweeney‚ & Williams‚ 1999; Daniel & Terrell‚ 1995). Again‚ however‚ the presentation is somewhat technical and developed through formulas‚ and is restricted to simple one-sample tests involving a mean or binomial proportion as the
