Scientists at the University of Bristol have discovered why fulminating gold—the world's first known high explosive—produces a purple smoke when it detonates, solving a 400-year-old alchemy puzzle. Fulminating gold was first discovered by alchemists in the 16th century. It is a mixture of a number of different compounds, with ammonia providing the majority of the material's explosive power. German alchemist Sebald Schwaertzer noted the unusual purple smoke given off when fulminating gold was detonated in 1585, and the material was later studied by leading figures of chemistry in the 17th and 18th centuries, including Robert Hooke and Antoine Lavoisier. But while the chemistry of the fulminating gold recipe has been understood for centuries, one question remained unanswered—why does its detonation produce purple smoke?

Bromocresol green (BCG) is a dye that is used in chemistry and analytical chemistry as a pH indicator in acid-base titration and in thin-layer chromatography staining solutions to visualize acidic compounds. Generally, the indicator can be prepared by dissolving BCG in an ethanol solution.

Is there a good way to get access to a mass spectrometer as an amateur chemist? I want to synthesize e.g. aspirin and verify the purity

(I understand that this is not the same as it being safe to take if the mass spectrometer only shows peaks corresponding to the product. I'd still be curious)

Hey, I’m a new user in Tumblr and I just have started to discover digital art, but I’d still really like to try sharing my fun stuff here.

So, this is my humanization of analytical chemistry.

Here she is:

🌟In the head and laboratory there is complete order, peace and accuracy up to seven decimal places, but this wonderful owner of the lab is trying to express herself and move away from the impeccable image of a “bore” as best she can.

🌟Steals ethanol and indicators from organic chemistry lab.

🌟Remembers absolutely all formulas for calculations by heart, good at mathematics.

🌟The only one who doesn’t mock inorganic chemistry.

🌟Gets very angry and upset if someone harshly rounds up the results of her laboratory calculations.

I see her only this way!

Role of Potency, Purity and Assay in Pharmaceuticals Analysis

Terms like Purity, potency and Assay are widely used in Analytical research and Quality control departments in Pharmaceutical Industries. Analytical Scientists and Quality control Chemists have a lot of confusion related to Purity, potency and Assay. Check out this post to know the answer to the following questions: What is purity? What is potency? What is assay? What are the differences among purity, potency and assay? Read more

Chemistry’s Chameleon: The Self-Repairing Marvels of Chemical Gardens

Chemists have been enamoured with the vibrantly coloured, coral-like structures that develop when combining metal salts in a tiny vial since the mid-1600s.

To date, scientists have been unable to simulate the functioning of these ostensibly straightforward tubular structures, known as chemical gardens, or the patterns and laws that control their development. Oliver Steinbock, an associate professor of chemistry and biochemistry at FSU, described it as "very interesting in a materials context." They don't develop as crystals do. A crystal grows and has lovely, pointed corners.

Chemical gardens typically develop when metal salt particles are added to a silicate solution. A semipermeable membrane that erupts upward in the solution as a result of the dissolving salt's reaction with the solution gives the structure, which resembles coral in appearance, a biological appearance.

The chemistry is associated with the development of hydrothermal vents as well as the corrosion of steel surfaces, where insoluble tubes can develop. The researchers were able to simulate a variety of distinct shape patterns, some of which resembled flowers, hair, spirals, and worms thanks to the constriction between two layers.

The designs could be made up of self-extending filaments, loose particles, or folded membranes, for instance.  The self-healing properties of the material were also shown by the model, which supported observations that fresh membranes expand in response to microbreaches.

Gas chromatography (GC) in analytical chemistry is a common type of chromatography where the mobile phase is a gas and the stationary phase is separated as a vapour. The instrumentation of gas chromatography is given above picture for more about Gas chromatography
