Several interesting properties of helium were discovered in the ensuing years. Sodium collected at the cathode. This very soluble salt has been leached into the oceans over the lifetime of the planet, but many salt beds or ‘lakes’ are found where ancient seas have evaporated. Potassium and Sodium Discovered In 1807, Sir Humphry Davy, the British scientist, tried to prove his idea that potash (potassium hydroxide, KOH) and soda (sodium hydroxide, NaOH) were actually very reactive, oxidized metals. Because sodium is extremely reactive, it never occurs in the free state in Earth’s crust. He discovered that he could separate out the sodium from compounds by using electricity. In 1807, at the Royal Institution, London, a few days after isolating potassium for the first time, he isolated sodium for the first time by electrolysis of dried sodium hydroxide, which had been very slightly moistened. ". Interesting Facts About Sodium. In 1806 Sir Humphry Davy discovered that chemical bonding was electrical in nature and that he could use electricity to split substances into their basic building blocks – the chemical elements. Sir Humphry Davy is credited with being the first to discover sodium as he was the first person to isolate the metal from caustic soda in 1807.

The sodium atom has a radius of 185.8 pm and a Van der Waals radius of 227 pm. He sent an electrical current through molten Sodium-Hydroxide. Sometime prior to the autumn of 1803, the Englishman John Dalton was able to explain the results of some of his studies by assuming that matter is composed of atoms and that all samples of any given compound consist of the same combination of these atoms. 40 terms. In 1807 Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide (NaOH). This discovery, later, led to the knowledge of extracting sodium chloride. Sodium bicarbonate, also known as baking soda or sodium hydrogen carbonate, is a crystalline solid. When the vinegar and ashes were mixed it created a solution that helped to prepare leather. Sodium Hypochlorite, an active ingredient of bleach was officially discovered in 1785 by an Italian-born French chemist named Claude Louis Berthollet. 11.
