Many chemists had speculated the presence of an unknown element having properties similar to chlorine in metal fluorides. In fact, Humphry Davy, a Cornish chemist, while trying to isolate it from hydrochloric acid, fell ill. In 1869, the British chemist George Gore passed an electric current thr...
In 1798, he dissolved the mineral in hydrochloric acid to create a mixture, precipitated lead to filter it off, and then successfully isolating chromium from the remaining filtrate [1]. Since the new element could produce a wide range of colors in solution, he called it chromium after the ...
It does not react with some acids, such as hydrochloric or cold sulfuric acid. But it does become more reactive with hot acids, such as hot sulfuric and nitric acids. Vanadium is special in that it acts like a metal in some cases, and as a non-metal in other cases. Metals are ...
