Antoine Lavoisier, considered the Father of Modern Chemistry, played a significant role in disproving the concept of phlogiston through his research on combustion and the discovery of oxygen. His experiments led to the development of the modern understanding of combustion and the role of oxygen in chemical reactions.
What else can I help you with?
Who eventually disproved the idea of phlogiston?
Antoine Lavoisier is credited with disproving the idea of phlogiston through his experiments on combustion and chemical reactions in the late 18th century. He showed that combustion actually involves the combining of oxygen with a substance rather than the release of phlogiston as believed earlier.
Did chemists believe in the phlogiston theory?
Yes, chemists believed in the phlogiston theory in the 17th and 18th centuries. It was thought that when substances burned, they released a substance called phlogiston. However, the theory was eventually disproven with the development of modern chemistry.
What are the bad points of the Phlogiston theory?
The Phlogiston theory was unable to explain certain chemical reactions, such as the combination of metals with oxygen. It also lacked experimental support and was eventually replaced by the more accurate oxygen theory of combustion. Additionally, the concept of phlogiston was found to be vague and arbitrary.
What was the evidence of phlogiston theory?
One piece of evidence for the phlogiston theory was the observation that combustion released a substance called "phlogiston" from burning materials, leaving behind ash. Another piece of evidence was the weight gain of metals when they were heated in air, which was believed to be due to the absorption of phlogiston. However, the theory was eventually disproven with the discovery of oxygen and the understanding of oxidation.
Why was the phlogiston unsatisfactory?
The concept of phlogiston was unsatisfactory because it failed to explain observations in chemistry, such as the increase in weight of metals when they rusted or burned. It was eventually replaced by the theory of combustion with oxygen based on more experimental evidence.

What was the religious sect that disaproved of shakespeares plays?
The Puritans.
Who disaproved of the 13th Amendment?
Southern states and slave holders.
What element was discovered in 1775?
Phlogiston was a theoretical substance proposed in 1667 by Johann Joachim Becher as a key feature of his phlogiston theory. It was supposed to be released during combustion and related processes. However, the concept was eventually disproven with the development of modern chemistry.
Was there evidence to prove the phlogiston theory correct?
The phlogiston theory was widely held in the 17th and 18th centuries to explain combustion and oxidation. However, it was eventually disproven with the discovery of oxygen by Lavoisier. This discovery provided a more accurate explanation for the process of combustion.
What is the mixture of calx and phlogiston?
lead calx + phlogiston = metallic lead
What did scientist think phlogiston was?
Phlogiston can be defined as "a hypothetical substance once believed to be present in all combustible materials and to be released during burning." Chemistry was so underdeveloped at the time Antoine Lavoisier gained interest in it that it could hardly be called a science. The prevailing view of combustion was the Phlogiston Theory which involved a weightless or nearly weightless substance known as phlogiston. Metals and fire were considered to be rich in phlogiston and earth was considered phlogiston poor. The following were the main theories put forward for 'phlogiston': * Weight loss when combustibles are burned because they lose phlogiston * Fire burns out in an enclosed space because it saturates the air with phlogiston * Charcoal leaves very little residue when burned because it is made mostly of phlogiston * Animals die in an airtight space because the air becomes saturated with phlogiston * Some metal calxes turn to metals when heated with charcoal because the phlogiston from the charcoal restores the phlogiston in the metal
