Joseph Black, a Scottish chemist, was born in Apr. Black discovered in 1754 that when you heat magnesia alba (magnesium carbonate), it loses weight. The weight loss was due to a “air” that is not released during heating, according to him. The same air could be extracted from other minerals, such as limestone. In a paper published by Black, he referred to his new gas, which ergot into granular matter, and the Philosophical Society of Edinburgh.
How Did Joseph Black Discover Magnesium – Answer & Related Questions
Joseph Black, a Scottish chemist, was born in Apr. The year 1728. Black discovered that when you heat magnesia alba (magnesium carbonate), it loses weight, and he discovered that the weight loss was due to a “air” that is not released during heating.
What Compound Did Joseph Black Discover?
Black lived and worked in Edinburgh, Glasgow, and Aberdeen during the second half of the 18th century, a remarkable flourishing of intellectual life.
The results backed up his most important paper of his career, “Experiments on Magnesia Alba, Quicklime, and Some Other Alcaline Substances,” which was presented to the Philosophical Society of Edinburgh in 1755.
Magne salt was used in his earlier experiments, and for the first time, a planned cyclic series of quantitative experiments in which balancing was employed at all stages.
How Did Joseph Black Discover Specific Heat?
Scientists predicted that if one warmed a piece of ice to the freezing point, merely melted the icy material.
The ice did not melt as expected, but the majority remained, as well as a little water, at 0° C. Black told that the intended event didnot occur. The water warmed by several degrees over a period of time. Black based his reasoning in part on the fact that something that was not supposed to happen did not happen.
He solved a puzzling situation by noting that he had not barked when it was expected to.
