Fireworks combine chemical processes, from combustion to spectroscopy, to create spectacular displays. Discover what happens when the fuse is lit. Chemistry - Reactions - Learning Points. Fireworks involve combustion and exothermic...

Transition metals are the largest group in the periodic table. Find out what similarities they share, and how we make use of these metals. Chemistry - Periodic Table - Learning Points. Transition metals are found as a block in the middle...

We use a supersaturated solution of sodium ethanoate to demonstrate instant crystallisation. Sodium ethanoate is added to water and is then heated to allow all of the crystals to dissolve. When it is cooled it forms a supersaturated...

We use a Bunsen burner to burn different chemical salts to see how the flame colour changes. This shows that sodium burns with a yellow flame, lithium burns with a red flame, barium burns with a yellow-green flame and copper burns with a...

Halogens are hazardous to human life, yet they can also be very useful. How do they react when they meet other elements? Chemistry - Periodic Table - Learning Points. The halogens are the elements in Group 7 of the periodic table. The...

Why are there so many different kinds of salt, and does it really matter which one you use?

The lymphatic system consists of a complex network of lymphatic vessels, glands or nodes, and organs, such as the spleen and thymus, extending throughout the body. Through it flows a fluid called lymph. The lymphatic system has three...

This video explains the different types of tears and their composition, including the reason why tears are salty. It also delves into the science behind tear production and how it is controlled by the brain.

In this video, the speaker discusses a required practical activity on the chemistry specification which involves investigating how increasing the concentration of a reactant increases the rate of reaction by collecting a gas. The speaker...

We just learned about medicine in the Middle Ages, and the time period that follows is called the Renaissance. What advancements were made during this time? The most important figure in this period of medicine went by the name of...

The video explains how to prepare a soluble salt using acids and alkalis. The presenter explains the concept of titration and its importance in determining the exact amount of acid required to neutralize a base. Through the process of...

Through photosynthesis, plants take in carbon dioxide from the air and split it and use it (and water) to make carbohydrates. So surely plants can help us reduce carbon dioxide in the air? Possibly... But equally, the carbon in plants is...

The video is a lecture presentation on the purification of water experiments. The presenter carries out a series of short experiments to investigate the effect of distillation on the pH and salt content of seawater. The presentation...

Mark Bitterman challenges the common perception of salt as a mere commodity, revealing its rich variety and historical value comparable to gold in certain eras. Through his store, he showcases over 150 types of salts from around the...

Learn the basics about hard and soft water, the differences between these and where to find examples in everyday life.

Researchers from South Korea and Greenpeace East Asia have found that 90% of table salt sold around the world are contaminated with microplastics.

It talks about preparation, properties & structure of HCl, oxoacids of halogens & interhalogen compounds. It gives introduction of group 18 elements & their occurrence.

In this video, the presenter explains how to prepare soluble salts using insoluble reactants. They use the example of zinc oxide as the insoluble base and demonstrate the steps involved in reacting it with an acid to produce zinc...

In this video, the presenter explains how to make soluble salts. They begin by discussing state symbols and explaining how they can indicate whether a substance is soluble or insoluble. Then, they outline the steps for producing a salt...

The video is a lecture presentation on the process of making salts through experiments. The presenter demonstrates different bases, copper carbonate and copper oxide, and hydrochloric acid. The presenter explains the theory behind the...
