Chloride chemistry

Chemical explosion. Cork exploding out of a bottle of sparkling wine. There is no wine. The cork has exploded out due to an increase in pressure due to the production of gas in a chemical reaction

Sulphuric acid added to water
Concentrated sulphuric acid (H2SO4) being added to water. The hydration reaction of sulphuric acid is highly exothermic and can cause the water to boil

Litmus solution added to alkali
Litmus solution being added to an alkali. Litmus is an indicator, a chemical that has a different colour depending on whether it is in an acidic or alkaline environment. In alkalis it is purple/blue

Calcium flame test. Calcium burning in air, producing an orange flame. The colour of the flame is caused by electrons that have been excited to a higher energy state

Litmus solution added to acid
Litmus solution being added to an acid. Litmus is an indicator, a chemical that has a different colour depending on whether it is in an acidic or alkaline environment. In acids it is red

Sooty flame. Alkene (oct-1-ene) burning in a crucible with a sooty (smoky) flame. Alkenes are unsaturated (double bonded) organic molecules. The sooty flame is characteristic of alkenes

pH measurement of oxide solutions
pHs of oxide solutions. Aqueous solutions of the oxides of some elements with universal indicator (UI) added to show their pH (acidity). The element forming each oxide is labelled

Sulphuric and ethanoic acid. Comparison of a strong and a weak acid. Sulphuric acid (H2SO4) is an important industrial chemical. It is used in petroleum refining and paint and fertiliser production

Burning sugar on a spoon

Iron filings in pure oxygen
Iron filings on a combustion spoon in a jar of pure oxygen. No reaction is occurring here as iron is not a very reactive metal

Mass-spring system. This system consists of a loaded trolley tethered between two clamp stands by identical springs. Displacing the trolley to one side causes it to oscillate back and forth

In the realm of scientific discovery, laboratories have served as the birthplace of countless breakthroughs and innovations. From the pioneering work of Rosalind Franklin in unraveling DNA's structure to Nikola Tesla's electrifying experiments, these hallowed spaces have witnessed some of history's most remarkable scientific feats. Back in 1899, Nikola Tesla's laboratory crackled with bolts of electricity discharging through the air. This visionary inventor pushed boundaries and revolutionized our understanding of electricity, paving the way for modern power systems. His laboratory became a playground for his mind-bending experiments that would shape the world we live in today. Meanwhile, Marie Curie (1867-1934) tirelessly worked in her laboratory on groundbreaking research into radioactivity. Her tireless efforts led to numerous discoveries and earned her two Nobel Prizes – one in physics and another in chemistry. Her legacy continues to inspire generations of scientists who follow in her footsteps. The laboratory is not just a place for individual brilliance; it also serves as a hub for collaborative endeavors. At CERN, home to cutting-edge particle physics research, teams working on projects like the ATLAS detector and CMS detector come together to unlock secrets about our universe’s fundamental building blocks. Science has always relied on precise measurements, which brings us to tools like mass spectrometers and tungsten carbide slip gauge blocks C016 / 2042 used within laboratories worldwide. These instruments ensure accuracy when analyzing samples or calibrating equipment—a testament to meticulousness required by scientists across disciplines. A photograph enlarger stands as an emblematic symbol within any photography lab—an essential tool that allows photographers to bring their images from small negatives into larger prints while preserving intricate details captured through lenses. Laboratory clamps serve as unsung heroes holding apparatuses firmly together during experiments—often overlooked but indispensable components ensuring safety and stability throughout various procedures conducted within these sacred spaces dedicated solely to science.
