What is Monopropylene Glycol?

Monopropylene glycol – also known simply as propylene – is a viscous, colourless liquid with a distinct sweet taste (but please don’t drink it). Almost odourless, it’s both miscible with water and hygroscopic, i.e. it attracts and absorbs moisture.  The chemical formula of monopropylene glycol is C3H8O2, which can also be written as: CH3CH(OH)CH2OH This formula tells us that it has two...

What is Potassium Hydroxide?

Potassium hydroxide (KOH) – which you might also hear called caustic potash or lye – is an inorganic compound. Just like other strong bases, it’s highly caustic and completely dissociates into ions when dissolved in water. The other seven strong bases include: LiOH (lithium hydroxide) NaOH (sodium hydroxide) Ca(OH)2 (calcium hydroxide) CsOH (caesium hydroxide) Sr(OH)2 (strontium hydroxide) RbOH (rubidium hydroxide) Ba(OH)2 (barium hydroxide). Potassium hydroxide is sold in...

Is Potassium Hydroxide Harmful to the Environment?

Just like many inorganic substances, potassium hydroxide doesn’t contain degradable functional groups. This means that it does not have a detrimental impact on the biological oxygen demand in water. It does, however, dissociate into ions when dissolved in water, which can elevate the pH level of systems that do not have sufficient buffers. If a large quantity of an alkaline...

How is Phosphoric Acid Made?

Phosphoric acid (H3PO4) is an inorganic compound that can be made through both wet and dry processes. The former involves the treatment of sulphuric acid, while the latter uses phosphate ore.  Also called orthophosphoric acid, phosphoric acid is a solid white crystal at room temperature. However, it’s more commonly available as an 85% aqueous solution, which is colourless, viscous, and...

About The Chemistry Blog

At The Chemistry Blog, we want to inform and educate people about chemistry, the chemical industry, and the uses, benefits, and applications of different chemicals, from methylene chloride to toluene to ethyl alcohol. No matter what it is you’re looking for, you’ll find plenty of chemical information here.

The Chemistry Blog is also home to a massive range of educational resources. Whether you’re studying for your upcoming GCSE or A level exam, or want to know more about how to pursue a degree in chemistry, there’s a wealth of information at your fingertips. Beyond this, our series of articles on apprenticeships in the chemical industry help equip aspiring scientists with the knowledge they need to take that next step in their career.  

The Chemistry Blog also provides information on specific fields in the chemical industry, from biotechnology to biochemistry to analytical chemistry, and explores the science behind key topics and chemical phenomena, like chemical changes and solubility. Plus, if you’re looking to grapple with more complex subjects, feed your appetite with articles like the decomposition of hydrogen peroxide or the reaction between hydrochloric acid and sodium thiosulphate.

But you don’t have to be a science pro or student to enjoy what we have on The Chemistry Blog. Have you ever wondered about the chemicals in swimming pools or oven cleaners? Do you want to get the most out of that jar of baking soda in your cupboard, or learn how to remove sticky labels using some rubbing alcohol? The Chemistry Blog is home to tons of articles that explore the applications and science behind common household chemicals so that you can better understand the things you use everyday. So, whether you’re a student, a science buff, or simply curious, there’s something for everyone on The Chemistry Blog!
