1. Decomposition and Synthesis Reactions
Elements and compounds multiply and new compounds form through the processes of decomposition and synthesis reactions. Learn about these reactions, understand how they occur, and explore their equations.
2. The Arrhenius Definition of Acids and Bases
The Arrhenius definition of acids and bases is based on compounds that produce either hydrogen ions or hydroxide ions respectively in a solution. Discover the differences between Arrhenius acids and Arrhenius bases and between strong and weak acids and bases.
3. The Bronsted-Lowry and Lewis Definition of Acids and Bases
Chemist Johannes Bronsted and scientist Thomas Lowry proposed that an acid should be defined as a substance that can donate a proton, while a base is any substance that can accept protons. American chemist G.N. Lewis proposed a different theory. Learn about three popular scientific definitions of acids and bases.
4. Neutralization and Acid-Base Reactions
Ions and molecules may experience neutralization and acid-base reactions. Learn about these processes and the Bronsted-Lowry definition of conjugate acid and conjugate base, and explore the definitions of amphoteric and neutral as they pertain to pH.
5. Dissociation Constant and Autoionization of Water
The autoionization constant is used to determine the concentration of either hydroxide or hydronium ions in a solution. Explore autoionization of water, the Kw constant, and how to determine concentrations of ions.
6. The pH Scale: Calculating the pH of a Solution
In chemistry, the pH scale is used to measure acidity on a scale of 0-6 for acids, 7 for neutral, and 8-14 to represent basic. Take an in-depth look into calculating the pH of a solution, and explore the role of hydronium and hydroxide ion concentrations in this process.
7. Weak Acids, Weak Bases, and Buffers
Hydrogen ions, given away by acids, can be strong or weak acids. Learn more about weak acids, weak bases, buffers, conjugate acid bases, and the roles of acidity constant and pKa.
8. Coordination Chemistry: Bonding in Coordinated Compounds
Coordination chemistry studies compounds with central atoms that are surrounded by ligands. Explore coordination chemistry and learn about bonding in coordinated compounds, and recognizing the shapes of coordinated compounds.
9. Precipitation Reactions: Predicting Precipitates and Net Ionic Equations
A precipitation reaction is a process during which two reactants form a precipitate. Discover what precipitates are, and learn about the solubility rules, net ionic equations, and examples of net ionic equations and their role in predicting precipitates.
10. Assigning Oxidation Numbers to Elements in a Chemical Formula
Oxidation is an important part of chemical reactions. Learn about oxidation, as well as oxidation number rules, and assign oxidation numbers to elements in a chemical formula, including neutral compounds and ions.
11. Balancing Redox Reactions and Identifying Oxidizing and Reducing Agents
A redox reaction is a chemical reaction that involves a transfer of electrons and changes in oxidation number. Learn about redox reactions, and identify oxidizing and reducing agents, and explore the process to write and balance a redox reaction equation.
12. The Activity Series: Predicting Products of Single Displacement Reactions
A single displacement reaction is when an element in a compound is replaced by a similar element. An activity series is an organized list that describes how each element reacts with other elements. Learn about single displacement reactions, activity series, and how to use an activity series table to predict the products of single displacement reactions.
13. Electrochemical Cells and Electrochemistry
Electrochemical cells are part of electrochemistry. Explore the parts of an electrochemical cell, the definition of an electrochemical cell diagram, the functions of the anode and the cathode, and how to make a homemade battery.
14. Cathode and Anode Half-Cell Reactions
Electrochemical reactions are comprised of two half-reactions, anode electrode & cathode electrode, that are added together to produce the full cell reaction. Learn about electrode half-reactions, corrosion, and how to use half-reaction formulas to calculate cell voltage potential.
15. Writing and Balancing Combustion Reactions
A combustion reaction occurs when a substance reacts with oxygen and releases a large quantity of energy in light and heat form. Learn how to write and balance equations for combustion reactions.
16. Corrosive: Definition & Examples
Corrosives are usually strong acids or bases and exist in almost every workplace and home. Learn more about the definition, examples, hazards, and safety measures related to corrosives.
