Starting out in chemistry and looking for information to expand your knowledge? In this section, you will find the necessary basics and many interesting facts about chemistry!
Elements classified in group 1 of the periodic table, that is lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr), are generally called lithium group elements. Given their strong metallic properties and the ability to form strong basic (alkaline) hydroxides, sometimes they are also referred to as alkali metals. What else […]
The elements from group 17: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At) are defined as halogens. What are the characteristics of halogens? Where do they occur and how can we use them? Read more in the article below!
The elements in group 16 of the periodic table are jointly referred to as chalcogens or the oxygen family. They include oxygen, sulphur, selenium, tellurium and polonium, and the group’s name comes from the first chemical element in the group. In this spectrum, we can observe a noticeable change in chemical properties along with the […]
Water is a compound that is most widely present in the world. It forms the basis of life on Earth. It is also an essential part of our daily lives. In order for its use – especially for drinking purposes – to be safe, the parameters of water quality must meet some specific criteria. One […]
Next to alkanes, alcohols, phenols or ketones, amides are yet another group of organic compounds that are characterised by specific properties. Amides are usually formed by the reaction of carboxylic acids with amines. These are chemical compounds that are common in nature or are obtained through synthetic chemical processing. With their numerous advantages, they are […]
Chemically speaking, ethylene oxide is the simplest of cyclic ethers, also known as epoxides. Its importance in various industries is evidenced by the annual production volume of this chemical compound. It is used primarily as an intermediate in the production of industrial chemicals such as ethylene glycol, as a fumigant in certain agricultural products, and […]
In nature, amino acids are a vast group of organic compounds. These are substances that contain at least one amine group and one carboxyl group in their structure. They also play an important role in the human body. They support a number of biochemical processes responsible for keeping you fit and healthy, they are the […]
Redox reactions, or oxidation-reduction reactions, are reactions in which the oxidation states of selected elements contained in the reacting chemicals is altered. This is because individual atoms are able to exchange electrons with each other. The oxidation process always occurs simultaneously with the reduction. Reactions of donating and accepting electrons by atoms are written as […]
One of the criteria by which chemical reactions can be divided is their rate of progression. Broadly generalising, it can be said that, in chemistry, we are dealing with reactions that proceed at high speed (such a process is often visible to the naked eye) and those that proceed so slowly that they are almost […]
We fashion our Academy based on the needs of our users. We study their preferences and analyse the chemistry keywords through which they search for information on the Internet. Based on this data, we publish information and articles on a wide range of issues, which we classify into various chemistry categories. Looking for answers to questions related to organic or inorganic chemistry? Or maybe you want to learn more about organometallic chemistry or analytical chemistry? Check out what we have prepared for you! Keep up to date with the latest news from PCC Group Chemical Academy!
