Aqua regia is a highly corrosive mixture of concentrated nitric acid and hydrochloric acid. With the ability to dissolve noble metals, it was once used by alchemists on their quest to find the philosopher’s stone. Properties of Aqua Regia Aqua regia appears as a yellow-orange fuming liquid. The presence of nitric and hydrochloric acid makes this substance extremely corrosive, especially to metals...
Sodium hydroxide (NaOH) is a strongly alkaline compound that appears as a white solid. It is commonly used in the manufacture of soap and detergents, but did you know that it can also help unblock your sink? Here's how... Use Sodium Hydroxide to Unblock Your Sink As a strong base that is very reactive, there are several ways that sodium hydroxide can...
Sodium hydroxide (NaOH) is a strongly basic organic compound that is also very hygroscopic. Also known as caustic soda or lye, it reacts with a number of compounds to produce very different results. Dissolving in Water Sodium hydroxide ionises when it is dissolved in water. While this may not necessarily be a chemical reaction, it is an important characteristic of how this...
Also known as caustic soda or lye, sodium hydroxide is a diverse chemical compound that is used in the manufacture of everyday products like soaps, detergents and paper. It was even used by a famous serial killer to help destroy the evidence... Properties of Sodium Hydroxide Sodium hydroxide is an inorganic, white solid that is strongly alkaline. As an ionic compound, it...
Propan-1-ol and propan-2-ol are both alcohols that share the same general chemical formula (C3H8O), so what is the difference between them exactly? It all comes down to their atomic arrangement and how the hydroxyl group is positioned.In a nutshell, the difference between propan-1-ol and propan-2-ol is the position of their respective hydroxyl (-OH) groups. Propan-1-ol has an –OH group attached...
Sodium thiosulphate (Na2S2O3) is considered one of the most important medicines in the health system because of its ability to treat rare diseases, like pityriasis versicolour, calciphylaxis and, most famously, cyanide poisoning.Cyanide poisoning is very rare yet very sinister. It works by depriving cells of oxygen which leads to the death of critical cells. The properties of sodium thiosulphate make...
Sodium thiosulphate (Na2S2O3) is an inorganic salt compound that is chiefly used as an antidote for cyanide poisoning. Recognised as one of the most important medicines in the health system, it has several medical uses and a range of interesting properties. Properties Also known as sodium hyposulfite or simply as hypo, this compound appears in two forms: anhydrous and pentahydrate. However,...
Hydrochloric acid (HCl) may be the simplest chlorine-based acid, but it is still strongly corrosive. We've written about the history behind and properties of hydrochloric acid, so this week we thought we’d take a look into its five most popular uses.But limiting the uses of hydrochloric acid to five is not an easy task. Known as a ‘workhorse’ chemical, this compound...
Hydrochloric acid (HCl) is a corrosive and strongly acidic solution that is made by dissolving gaseous hydrogen chloride in water. It is made industrially as well as in the body. Properties of HCl Hydrochloric acid is the simplest chlorine-based acid that contains water. In spite of its acidity, it is also the least hazardous strong acid to handle because of its non-toxic...
