How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

Advanced Inorganic Chemistry is designed to give you the knowledge to explain everyday phenomena of inorganic complexes. The student will study the various aspects of their physical and chemical properties and learn how to determine the practical applications that these complexes can have in industrial, analytical, and medicinal chemistry. Upon successful completion of this course, the student will be able to: Explain symmetry and point group theory and demonstrate knowledge of the mathematical method by which aspects of molecular symmetry can be determined; Use molecular symmetry to predict or explain the chemical properties of a molecule, such as dipole moment and allowed spectroscopic transitions; Construct simple molecular orbital diagrams and obtain bonding information from them; Demonstrate an understanding of valence shell electron pair repulsion (VSEPR), which is used for predicting the shapes of individual molecules; Explain spectroscopic information obtained from coordination complexes; Identify the chemical and physical properties of transition metals; Demonstrate an understanding of transition metal organometallics; Define the role of catalysts and explain how they affect the activation energy and reaction rate of a chemical reaction; Identify the mechanisms of both ligand substitution and redox processes in transition metal complexes; Discuss some current, real-world applications of transition metal complexes in the fields of medicinal chemistry, solar energy, electronic displays, and ion batteries.

Organic chemistry is the discipline that studies the properties and reactions of organic, carbon-based compounds. The student will begin by studying a unit on ylides, benzyne, and free radicals. Many free radicals affect life processes. For example, oxygen-derived radicals may be overproduced in cells, such as white blood cells that try to defend against infection in a living organism. Afterward the student will move into a comprehensive examination of stereochemistry, as well as the kinetics of substitution and elimination reactions. The course wraps up with a survey of various hetereocyclic structures, including their MO theory, aromaticity, and reactivity. Upon successful completion of this course, the student will be able to: Describe free radicals in terms of stability, kinetics, and bond dissociation energies; Describe the stereochemistry and orbitals involved in photochemical reactions; Describe enantiomers, diastereomers, pro-S and pro-R hydrogens, and Re/Si faces of carbonyls; Perform conformational analysis of alkanes and cyclohexanes; Describe reaction mechanisms in terms of variousparameters (i.e.,kinetics, Curtin-Hammet principle, Hammond postulate,etc.); Describe the chemistry of the heterocycles listed in Unit3 in terms of molecular orbital theory, aromaticity, and reactions.

Agar Cell Diffusion
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating

All biological cells require the transport of materials across the plasma membrane into and out of the cell. By infusing cubes of agar with a pH indicator, and then soaking the treated cubes in vinegar, you can model how diffusion occurs in cells. Then, by observing cubes of different sizes, you can discover why larger cells might need extra help to transport materials.

Analytical chemistry is the branch of chemistry dealing with measurement, both qualitative and quantitative. This discipline is also concerned with the chemical composition of samples. In the field, analytical chemistry is applied when detecting the presence and determining the quantities of chemical compounds, such as lead in water samples or arsenic in tissue samples. It also encompasses many different spectrochemical techniques, all of which are used under various experimental conditions. This branch of chemistry teaches the general theories behind the use of each instrument as well analysis of experimental data. Upon successful completion of this course, the student will be able to: Demonstrate a mastery of various methods of expressing concentration; Use a linear calibration curve to calculate concentration; Describe the various spectrochemical techniques as described within the course; Use sample data obtained from spectrochemical techniques to calculate unknown concentrations or obtain structural information where applicable; Describe the various chromatographies described within this course and analyze a given chromatogram; Demonstrate an understanding of electrochemistry and the methods used to study the response of an electrolyte through current of potential.

Analytical Chemistry 2.0
Unrestricted Use
CC BY
Rating

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.

Analyzing pH: Comparing Citrus Fruits, Stain Removers and a Green Product
Conditional Remix & Share Permitted

The students will analyze the pH of four citrus fruits: lime, lemon, orange, and a grapefruit, and then they will analyze the pH of four different types of stain removers:
Shout Advanced, Spray 'n Wash Max, Oxi Clean Laundry, and Clorox Oxi Magic. Using their learned information, they will predict and then analyze the pH of a final cleaning solution Bathroom Lime & Scale Remover, which is a Green product.

Students will use two methods of determining the pH for comparison. This will be done utilizing pH litmus paper and creating a cabbage indicator solution.

Students will also read labels, list the first few ingredients, and identify sales tactics used for their products such as eye-catching phrases. (Language Arts)

Finally, students will discuss and share their results as a class. Students need to answer what do citrus fruits have to do with cleaning? What product is most effective? Students need to support their answer with data from their experiment.

CC BY-NC-SA
Rating

The purpose of this video lesson is to expand the student's knowledge about enzymes by introducing the antioxidant enzymes that are intimately involved in the prevention of cellular damage and eventual slowing of the aging process and prevention of several diseases. Students will learn that natural antioxidant enzymes are manufactured in the body and provide an important defense against free radicals. The topic of free radical action is introduced, covering how they are constantly generated in living cells both by ''accidents of chemistry'' and also by specific metabolic processes.
