Chemistry is the study of matter. Our understanding of chemical processes thus depends on our ability to acquire accurate information about matter. Often, this information is quantitative, in the form of measurements. In this lab, you will be introduced to some common measuring devices, and learn how to use them to obtain correct measurements, each with correct precision. A metric ruler will be used to measure length in centimeters (cm).

Short Description:
The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning.

In this activity, students use the virtual lab to create 500mL of 3M HCl solution from a concentrated stock solution of 11.6M HCl. They must first calculate the correct volumes of 11.6M HCl solution and water to mix together to create the final solution. Next, they prepare the solution using the appropriate glassware, and then can check their answer using the concentration viewer in the solution info panel.

In this field-based exercise, students were given a tour of an abandoned mine site and asked to utilize a set of field measurements to describe the spatial details of metal transport. This drew on previous experience with field measurements and prompted them to work together to solve an observed chemical evolution of a contaminated brook. The exercise is an excellent example for students to bring together acid-base chemistry, redox chemistry, and thermodynamic concepts together to describe a reasonably complex system. The field component was completed in a full day, but we will be expanding this next fall for a 2 day exercise (weekend). The exercise was coupled with subsequent labs to complete analysis of the water samples and accomplish speciation calculations using PHREEQCI.

Intended Audience: This activity was used for an introductory Geochemistry class, which contained students from sophomore level to master's students. We took the trip in mid-October, about as late as possible in Vermont, after they had gained some previous field experience and lab work in addition to an in introduction to these principles in class.

Students research the acidification of freshwater streams and lakes, identify at least one of the sources, and determine how their daily activities contribute to the problem.

Adapt is an online homework system that exists within the LibreTexts platform. Instructors can create courses and assignments for students. Course shells for preparatory chemistry, general chemistry, analytical chemistry, and organic chemistry are available in the commons area.

Road deicers raise several environmental and cost concerns. In this activity students consider alternatives while investigating colligative properties.

In this activity students examine groundwater flow path based on hydraulic head data/ potentiometric surface and spatial variation of groundwater chemistry. Students analyze the data using AquaChem and Phreeqc which is integrated with AquaChem

Analytical chemistry spans nearly all areas of chemistry but involves the development of tools and methods to measure physical properties of substances and apply those techniques to the identification of their presence (qualitative analysis) and quantify the amount present (quantitative analysis) of species in a wide variety of settings.

Analytical chemistry is more than a collection of analytical methods and an understanding of equilibrium chemistry; it is an approach to solving chemical problems. Although equilibrium chemistry and analytical methods are important, their coverage should not come at the expense of other equally important topics. The introductory course in analytical chemistry is the ideal place in the undergraduate chemistry curriculum for exploring topics such as experimental design, sampling, calibration strategies, standardization, optimization, statistics, and the validation of experimental results. Analytical methods come and go, but best practices for designing and validating analytical methods are universal. Because chemistry is an experimental science it is essential that all chemistry students understand the importance of making good measurements.

As currently taught in the United States, introductory courses in analytical chemistryemphasize quantitative (and sometimes qualitative) methods of analysis along with a heavydose of equilibrium chemistry. Analytical chemistry, however, is much more than a collection ofanalytical methods and an understanding of equilibrium chemistry; it is an approach to solvingchemical problems. Although equilibrium chemistry and analytical methods are important, theircoverage should not come at the expense of other equally important topics.

My goal in preparing this textbook is to find a more appropriate balance between theoryand practice, between “classical” and “modern” analytical methods, between analyzing samplesand collecting samples and preparing them for analysis, and between analytical methods anddata analysis. There is more material here than anyone can cover in one semester; it is myhope that the diversity of topics will meet the needs of different instructors, while, perhaps,suggesting some new topics to cover.

This is Experiment #3 in the Analytical Chemistry Lab sequence at MSU Denver. In this experiment students will extract bismuth from pepto bismol and then quantify it using two techniques: gravimetry and flame atomic absorption spectroscopy.

This is Experiment #5 in the Analytical Chemistry Lab sequence at MSU Denver. In this experiment, students will use two methods to determine the concentration of two food dyes in a sports beverage.Spectrophotometric analysis with linear least squares regressionHigh Performance Liquid Chromatography (HPLC) analysisStudents will learn quantitative methods with spectroscopy and learn to interpret a chromatogram to create a calibration model. Then students will compare and contrast the methods and report their results in a technical write-up.

This open course with a new set of ancillary materials for OpenStax Chemistry was created under a Round Eleven Mini-Grant for Ancillary Materials Creation and Revision. The materials created in order to support faculty implementing OpenStax Psychology in the classroom include:

Lecture Slides
Chapter Checklists
Practice Problems
Newly-Created Videos

Along with these resources, the open course also contains a laboratory section with new instructional videos, a laboratory notebook and a sample notebook with responses, and experiments for each course.

In this problem set students are given Rb/Sr and 87Sr/86Sr data for whole rock and mineral samples from three granitic intrusions in the Sierra Nevada. They use these data (in EXCEL) to calculate isochron ages and initial ages for the intrusions and then interpret their results. This problem is intended to teach some spreadsheet skills (linear regressions, graphing) as well as having them think about the use of radiogenic isotopes.
