Investigation I: Graphical Determination of a Physical Value
2018-19 Chemistry 120/ Compound Prep & Analysis/Procedure 1 Investigation 3: Preparation and Analysis of a Compound Focus Questions: How can we determine the empirical formula of the potassium iron oxalate compound synthesized in lab? What is the percent yield of the synthesis reaction? Background Synthesizing compounds in the laboratory – especially those that are new, medically useful, or brightly colored – is an exciting facet of chemistry. However, determining the chemical formula of the compound produced can be a challenge. In this series of investigations, you will synthesize a complex compound and then use several techniques to determine the empirical formula of the compound. Overview The compound that will be synthesized has the general formula KaFeb(C2O4)c · dH2O, where a, b, c, and d, are integers that give the relative molar quantities of each component in the compound. The synthesized compound will be isolated by filtration and then analyzed for percent potassium, percent oxalate, and percent water, all over a period of several weeks. The percent iron will be found by difference once the percentages of the other three components are known. These percentages will then be used to calculate the empirical formula of the synthesized compound. Percent potassium determined by ion exchange Percent water determined followed by acid-base by dehydration titration KaFeb(C2O4)c · dH2O Percent iron determined by Percent oxalate determined difference after other three by reaction with cerium percentages are known Synthesis and Isolation of the Compound Preparation of NaOH Solution, Dehydration and Analysis for Potassium Pre-lab required reading Chemistry; an Atoms-Focused Approach: Sections 7.3-7.5, 7.7, and 8.5 – 8.8. -
The Calibration of Small Volumetric Laboratory Glassware

C. 20234 NBSIR 74-461 THE CALIBRATION OF SMALL VOLUMETRIC LABORATORY GLASSWARE Josephine Lembeck Institute for Basic Standards National Bureau of Standards Washington, D. C. 20234 December 1974 Final Prepared for Optical Physics Division Institute for Basic Standards Washington, D. C. 20234 U. S. DEPARTMENT OF COMMERCE, Frederick B. Dent, Secretary NATIONAL BUREAU OF STANDARDS, Richard W. Roberts. Director The Calibration of Small Volumetric Laboratory Glassware by Josephine Lembeck 1. INTRODUCTION , This article describes an acceptable procedure for calibrating burets, pipets and volumetric flasks of the types shown in figure 1. The physical characteristics of these items are indicated in Interim Federal Specifications NNN-B-00789a (GSA-FSS) , NNN-P- 00395a (GSA-FSSi NNN-F-00289a (GSA-FSS), and NBS Handbook 105-2. The general procedure is based upon a determination of the volume of water either contained in or delivered by the vessel. This volume of water is based upon knowledge of its measured mass and its tabulated density. Inasmuch as these calibration volumes, especially the delivery volume, may be altered by the manner in which the vessels are used, it is imperative that the user of the vessel employ the same techniques as those employed during calibration. The techniques of importance here are: 1. reading and adjusting meniscus 2. filling the vessel 3. draining the vessel. v These three topics will be covered in detail. -
Care and Handling of Cuvettes
FACT SHEET: CARE AND HANDLING OF CUVETTES Proper maintenance of quartz cuvettes is an essential part of spectrophotometric analysis. The following notes are based on the recommendations of Australian Standard AS 3753-2001. Cuvettes in regular use should be stored either: a) in a box lined with a suitably soft material (possibly one supplied by the manufacturer); b) immersed in distilled water; c) immersed in 1% v/v nitric acid. Before use, cuvettes should be cleaned to remove any accumulated residue. If the cuvettes appear clean, simply rinse several times with distilled water, then once with acetone (to prevent watermarks) and leave to air-dry in an inverted position (e.g. on a tissue) before use. Repeat the same process after use, and if maintained in this manner, then drastic cleaning measures ought to be prevented. If cuvettes do become heavily soiled, then the following solutions are recommended for soaking: a) Distilled water b) Mild, non-alkaline detergents (used at concentrations specified by the manufacturer) c) Ten percent acetic acid d) Cold concentrated nitric acid Cleaning with any of the above solutions can be improved by doing so in an ultrasonic bath, but make sure the cuvettes are supported to prevent rubbing against other surfaces or other cuvettes, as they could be scratched. Never use strong alkaline solutions, such as laboratory glassware detergent. When using cuvettes, do not touch the optical windows. All cuvettes have two opaque surfaces for handling purposes. Do not wipe the windows with paper tissues. Tissues are abrasive and may scratch the cuvette window, as well as leaving behind fibres and brightening agents (which will reduce transmission). -
Hand Washing Laboratory Glassware Study Summary
LABCONCO CORPORATION • 8811 PROSPECT AVENUE • KANSAS CITY, MO 64132 Hand Washing Laboratory Glassware Study By Odette Nolan, Product Manager, Labconco Corporation Summary Hand washing laboratory glassware can consume a high volume of water. Although automatic glassware washers are often touted as being more efficient in water usage than hand washing, published water usage studies have not addressed laboratory glassware washers, rather only residential washers and a 12 place setting set of dishes. Since hand washing dishes in a residential setting is far different than washing flasks and beakers in the lab, Labconco conducted a study to determine the quantity of water used to hand wash laboratory glassware. Three different workers of varying washing experience were given the task of hand washing the same 28 pieces of laboratory glassware (SEE TABLE 2) using a typical GMP washing protocol (SEE Procedure Section). The results of this data were compared to a commonly used preprogramed cycle of the Labconco line of Laboratory Glassware Washers, specifically the “GLASS” setting plus 1 purified water rinse. This setting, which is factory set to provide 2 wash cycles and 3 tap water rinses, has the option to add pure water rinses. Results show that an average of 119 L of water was consumed in a single hand wash of the 28 pieces of glassware, which took 15.56 minutes to complete, and 11.88 L of water for the purified water rinse, which took an additional 11.9 minutes (SEE Table 1). The side-by-side comparison shows an automated washer saved approximately 211L of water and approximately 24 min in wash time (SEE TABLE 1).
