Answers
Answer:
here is your answer .
Explanation:
William Nicholson is the scientist who show electrolysis of water produce Hydrogen and
oxygen bubbles .
plz mark me as brainliest .
Explanation:
In the early nineteenth century, William Nicholson and Anthony Carlisle sought to further Volta's experiments. They attached two wires to either side of Volta's battery and placed the other ends in a tube filled with water. They noticed when the wires were brought together that each wire produced bubbles. One type was hydrogen, the other was oxygen.
In 1785 a Dutch Scientist named Martinus Van Marum created an electrostatic generator that he used to reduce tin, zinc and antimony from their salts using a process later known as electrolysis. Though he unknowingly produced electrolysis it was not until 1800 when William Nicholson and Anthony Carlisle discovered how electrolysis works.
In 1791 Luigi Galvani experimented with frog legs. He claimed that placing animal muscle between two dissimilar metal sheets resulted in electricity. Responding to these claims, Alessandro Volta conducted his own tests. This would give insight to Humphry Davy's ideas on electrolysis. During preliminary experiments, Humphry Davy hypothesized that when two elements combine together to form a compound, electrical energy is released. Humphry Davy would go on to create Decomposition Tables from his preliminary experiments on Electrolysis. The Decomposition Tables would give insight on the energies needed to break apart certain compounds.
In 1817 Johan August Arfwedson determined there was another element, lithium, in some of his samples, however, he could not isolate the component. It was not until 1821 when William Thomas Brande used electrolysis to single it out. Two years later, he streamlined the process using lithium chloride and potassium chloride with electrolysis to produce lithium and lithium hydroxide.
During the later years of Humphry Davy's research, Michael Faraday became his assistant. While studying the process of electrolysis under Humphry Davy, Michael Faraday discovered two laws of electrolysis.
During the time of Maxwell and Faraday, concerns came about for electropositive and electronegative activities.
In November 1875, Paul Émile Lecoq de Boisbaudran discovered gallium using electrolysis of gallium hydroxide, producing 3.4 mg of gallium. That following December, he presented his discovery of gallium to the Academie des Science in Paris.
On June 26, 1886, Ferdinand Frederick Henri Moissan finally felt comfortable performing electrolysis on anhydrous hydrogen fluoride to create a gaseous fluorine pure element. Before he used hydrogen fluoride, Henri Moissan used fluoride salts with electrolysis. Thus on June 28, 1886 he performed his experiment in front of the Academie des Science to show his discovery of the new element fluorine. In the cost of trying to find elemental fluorine through electrolysis of fluoride salts, many chemists perished including Pauline Louyet and Jerome Nickels.
In 1886 Charles Martin Hall from America and Paul Héroult from France both filed for American patents, with Héroult submitting his in May and Hall’s in July.Hall was able to get his patent by proving through letters to his brother and family evidence that his method was discovered before the French patent was submitted. This became known as the Hall-Héroult process which benefited many industries because the price of aluminum had dropped from four dollars to thirty cents per pound.
Hope this helps u.....
