Titration Calculations Before you go any further, check that you can do the following… Calculate: Relative molecular masses from a given chemical formula Calculate: Number of Moles from the mass/RMM equation Manipulate: The number of moles equation to get the form you require. When you are confronted by a Titration calculation the first rule is: The Second rule is read through the question very carefully. The Third rule is read through the question carefully again! We are now going to look at a question and hopefully guide the unbelievers (henceforth known as infidels) through a titration calculation. The question: 10.0 cm3 of a solution of potassium hydroxide was titrated with a 0.10 M solution of hydrochloric acid. 13.5 cm3 of the acid was required for neutralization. Step 1 Write down everything you know. Hydrochloric Acid Potassium hydroxide Volume used = 13.5 cm3 Volume used = 10.0 cm3 Concentration = 0.10 M Concentration = TBD Step 2 Write the equation or as much as you know about it. Step 3 Step 4 Questions 1. 2.
Middle School Chemistry | Download Free Science Activities, Access Chemistry Multimedia, Find Information on Workshops Royal Society of Chemistry | Advancing the Chemical Sciences ChemTube3D Practical Chemistry.org This website is for teachers of chemistry in schools and colleges. It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry is a practical science. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5.
Mr. Guch Explains -- A Guch-a-riffic chemistry tutorial! Mr. Guch Explains I have good news and bad news. The bad news is that I'm not going to add to the list below anymore because it's a pain to get everything formatted for the Interwebs. The good news is that I'm going to start adding new questions in blog format over at . Check it out, and email me any questions you've got at email@example.com .

Lecture Demonstration Movie Sheets NOTE: The set-up and preparation information for most of these demonstrations is available in the Lecture Demonstration Manual by Bodner, Smith, Keys, and Greenbowe. John Wiley and Sons, Inc. ( prints updated editions on an irregular basis. Each sheet provides a quicktime video of the demonstration, a brief description of the materials used, pictures of the equipment used, observations, and explanations. Sheets described as "Under Construction" have no movies associated with them yet, but can still be useful for descriptions and reference material in the interim.

Chemistry Now The National Science Foundation (NSF) has joined forces with NBC Learn and the National Science Teachers Association (NSTA) to celebrate the International Year of Chemistry by creating "Chemistry Now"--a weekly, online video series that uncovers and explains the science of common, physical objects in our world and the changes they undergo every day. The series also looks at the lives and work of scientists on the frontiers of the 21st century... More. This video explains and illustrates the molecular structure of sodium chloride (NaCl) crystals; the structure and symmetry of crystal lattices; and why one crystalline solid, salt, melts another, ice. chemistry - dawnwelch7 Introductory Activity Rubric Matter and Its Changes Separating Mixtures Lab Information Packet Results: Sugar Crystals Paper Chromatography Tiny Salt Crystals in Crucible States of Matter Atoms, Ions, Isotopes, and Radioactive Decay Electromagnetic Spectrum Quiz Game The Periodic Table Ionic, Covalent & Metallic Bonds and Compounds Discovery Video "Water's Structure" Video (get login and password from Mrs. Naming CompoundsGame Naming Common Polyatomic Ions Game Chemical Reactions Redox Reactions Motion & Forces Energy Transformations Interdependence Developing Abilities for Scientific Inquiry
Chemistry Review Activities I re-organized the course during the 2014 - 2015 school year. Some review activities were moved to new units. This has resulted in a change to some of the file names, so direct links to the individual activities may need to be changed. These are not graded assignments. They are intended only as practice of concepts and vocabulary that are essential to your success in this course. Unit 0 - The Methods of Chemistry Unit 1 - Atomic Structure Unit 2 - Periodic Behavior and Ionic Bonding Element Classes Review - Unit 2 Benchmark #1 (Matching Activity) Element Classes Review 2 - Unit 2 Benchmark #1 (Multiple Choice) Element Classes Review - Unit 2 Benchmark #1.

Welcome to Virtlab! Virtlab is based on the simulations and guided exercises found in N. Simonson & Company's pioneering text: Dynamic Models in Chemistry by Daniel E. Atkinson (University of California, Los Angeles, CA), Douglas C. Brower, and Ronald W. McClard (Reed College, Portland, OR). Virtlab's browser requirements are quite high. Copyright (c) 1989 - 2011 N.
