Chemistry Techniques – Titration

It’s an analytical technique that can be used to find the concentration of a solution (the amount of a solute dissolved in it). I put this graphic together primarily to remind my A level students of some of the key aspects of titrations, but as well as being a handy guide for them, it’s a useful introduction to the technique for non-chemists too! Students are usually introduced to titrations in the context of reactions between acids and alkalis. As many of you might well recall, this is known as a neutralisation reaction. To measure the fixed volume of the acid solution, chemists often use pipettes. Once the solution is in the pipette, it’s then transferred to a conical flask.

Once you’ve got your acid of unknown concentration in the conical flask, it’s time to set up the burette with your alkali of known concentration. With both conical flask and burette filled, you’re ready to start the titration. Find chemistry lesson plans, labs, demos, activities and more for high, middle, and elementary school.

Chemistry — Cooler Than Absolute Zero!

The first on our list was hailed as the philosophers’ stone when it was discovered. 1. Phosphorus Phosphorus was the first element ever isolated scientifically. In 1669 Hennig Brand evaporated water from urine, then allowed the residue to fester for a few months. When he distilled the residue, one of the substances that appeared was phosphorus. Some alchemists thought Brand had discovered the philosophers’ stone! The Alchemist by Joseph Wright depicts Hennig Brand’s discovery of phosphorus. 2.

Carbon forms more compounds than any other element. Carbon’s ability to bond with other elements makes it the ideal basis for life, such as this excited gull. 3. Compound Interest. ChemGameTutor.

50 Awesome Chemistry Videos For The Busy Science Teacher

From the reactions that fuel the sun to the biology of our bodies to the technology in our gadgets, chemistry is at the heart of everything we do and is the central science that unites biology, physics, geology, astronomy, medicine, and countless other fields. Yet chemistry doesn’t always get the credit and recognition it deserves for playing such an awesome role in, well, everything. If you’ve been slighting chemistry, there’s no better time to give the field the credit it deserves than National Chemistry Week. Founded in 1987, the week-long event has helped bring awareness to the role chemistry plays both in our lives today and in our future. You can get in the spirit of the event by checking out a few (or all) of these amazing chemistry videos online.
