Laboratory Manual for Principles of General Chemistry 11th Edition covers two semesters of a general chemistry laboratory program. The material focuses on the lab experiences that reinforce the concepts that not all experimental conclusions are the same and depend on identifying an appropriate experimental procedure, selecting the proper apparatus, employing the proper techniques, systematically analyzing and interpreting the data, and minimizing inherent variables. As a result of "good" data, a scientific and analytical conclusion is made which may or may not "be right," but is certainly consistent with the data.

Experiments write textbooks, textbooks don't write experiments.

A student's scientific literacy grows when experiences and observations associated with the scientific method are encountered. Further experimentation provides additional "cause & effect" observations leading to an even better understanding of the experiment.

The 11th edition's experiments are informative and challenging while offering a solid foundation for technique, safety, and experimental procedure. The reporting and analysis of the data and the pre- and post-lab questions focus on the intuitiveness of the experiment.

The experiments may accompany any general chemistry textbook and are compiled at the beginning of each curricular unit.

An "Additional Notes" column is included in each experiment's Report Sheet to provide a space for recording observations and data during the experiment. Continued emphasis on handling data is supported by the "Data Analysis" section.

Safety: Lab safety and compliance with recent safety advisories and guidelines is emphasized throughout. Laboratory Safety and Guidelines outlines personal and lab safety rules and issues – self-protection, accidents, general lab rules, and work ethics.

Techniques and Safety Practices section includes Global Harmonized System (GHS) pictograms.

Experimental Procedures icons of each experiment cite cautions for handling various chemicals, proper disposal, and proper cleanup.

Prelaboratory Assignment questions ask students to review the safety issues for the experiment.

Laboratory Techniques and Safety Practices: Numbered icons at the beginning of each experiment and within Experimental Procedures reference basic laboratory techniques and enable students to complete the experiment safely and efficiently. The section also provides a full explanation of 17 basic general chemistry laboratory techniques used throughout the manual and integrates explanations of how the Global Harmonized System (GHS) pictograms further student training in safety.

Data Analysis: Unit conversion is added to support the key emphasis on presenting and analyzing experimental data. The seven parts of the Data Analysis section includes emphasis on the use and significance of sig figures and of data average, unit conversions, standard deviations, and relative standard deviations. Graphing guidelines are also included for construction of graphical data and their interpretations. These analytical techniques are found throughout the book’s margins.

Focus is on presenting reliable and interpretive data that is collected and analyzed.

Data documentation guidelines are presented for recording and reporting data. Suggestions for setting up a laboratory notebook are also provided.

Organization: Experiments are categorized according to general chemistry curricula and collected in Units. Each unit has a one-page summary of the curriculum components and techniques of the experiments. For example, all redox experiments are grouped in Unit 9: Oxidation-Reduction Systems and Analysis such that the sequential numbering of the experiments within this unit indicates a greater degree of complexity.

Report Sheets: Report Sheets included an “Additional Notes” column for compilation of observations and data recorded during the experiment to be submitted later in the Report Sheet entries. Data entries on the Report Sheet are distinguished from calculated entries. Students are encouraged to use appropriate software for analyzing and plotting. Downloadable Excel templates are available. 

Experiments and Dry Labs: 39 experiments and four “dry labs” are subdivided into 11 basic chemical principles collected in curricular units with Unit Opener for each that compiles the components and techniques of the experiments in that unit.

Appendices: 5 Appendices include conversion factors, names of common chemicals, vapor pressure of water, concentrations of acids and bases, and water solubility of inorganic salts.

6 Major Sections:

• Laboratory Safety and Guidelines

About The Role

ABOUT ROCKET LAB

Rocket Lab is a global leader in launch and space systems. The rockets and satellites we build and launch enable some of the most ambitious and vital space missions globally, supporting scientific exploration, Earth observation and missions to combat climate change, national security, and exciting new technology demonstrations. Our Electron rocket has provided reliable access to orbit since 2018, becoming one of the most frequently launched rockets in the world. Neutron will be our next rocket on the launch pad, an advanced 13-tonne payload class, reusable rocket to launch the mega constellations of the future. Our space systems business includes our extensive line of satellites and components that have enabled more than 1,700 missions including the James Webb Space Telescope, NASA Psyche Mission, Artemis I, Mars Ingenuity helicopter, and more.  

Join our pioneering team and launch your career to new heights!

SPACE SYSTEMS    

Rocket Lab’s Space Systems team is responsible for every satellite and satellite component made by Rocket Lab: from complete satellites destined for missions to the Moon and Mars, to the individual components and subsystems that make up a satellite like solar panels, flight software, reaction wheels and star trackers, separation systems, radios, and more. Our Space Systems team is made up of engineers, technicians, and designers who design, create, and put together our own satellites for missions across the commercial, government, and defense sectors, or who build and assemble satellite hardware and software that supports other satellite missions.
