Acid and Base Equilibrium

Acid and Base Equilibrium From the traditional definition an acid is a species that produces hydrogen ions and a base produces a hydroxide ion when dissolved in a solvent. Through the exploration of acid-base reactions you will notice that these simple definitions aren’t accurate enough and will need to be Read more…

Chemical Reactions

Chemical Reactions A chemical bond represents the forces that hold together different atoms to produce molecules, compounds and solids. From these bonded atoms we form compounds that possess different properties and naming systems. From the images below you can review these concepts of chemical bonds, molecular models, nomenclature and calculations Read more…

Solutions

Chemistry of Solutions The chemistry of solutions involves the discussion of the intermolecular forces, the polarity and solubility of compounds, and the interconversions between molarity, molality, mass percent, ppm, ppb and mole fraction. In addition the solubility of gases can be examined by Henry’s Law and changes in physical properties Read more…

Chemical Kinetics

Chemical Kinetics Chemical Kinetics examines the rate of a chemical reaction by looking at how quickly reactants break down to form products. The examination of a reaction’s rate includes topics such as General or Average Rate, Rate Law, the Integrated Rate Laws, the Arrhenius Equations, reaction mechanisms and energy diagrams. Read more…

Atoms & Elements

Atoms & Elements The Periodic Table is a representation of the different elements that exist in order of increasing atomic mass. Within a given atom or ion we have a set number of protons, neutrons and electrons and the Periodic Table gives the average mass of the elements’ isotopes. Below Read more…

Percent Error

Precision and Accuracy When we investigate the quality of an experimental decision or calculation we take into account two major principles: The first principle, which deals with the reproducibility of our calculations, is called precision. The second principle called accuracy deals with how close our measured calculation is to the Read more…

Molecular vs Electron Geometry

Molecular and Electron Geometry The shape of a chemical compound is essential in understanding its polarity and by extension its intermolecular forces. For now let’s review the key differences and similarities that exist with the molecular geometry and electron geometry of Lewis Dot Structures. Molecular & Electron Geometry
