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.
What else can I help you with?
What evidence is there to prove phlogiston theory of burning was correct?
The phlogiston theory has been debunked by the discovery of oxygen. When materials burn, they combine with oxygen, not phlogiston as believed in the theory. The understanding of combustion and oxidation provided by oxygen led to the rejection of the phlogiston theory.
What evidence was there to suggesst that the phlogiston theory was correct?
Support for the phlogiston theory came from observing that substances such as wood and charcoal released a substance (phlogiston) when burned, leaving behind ash. This was believed to explain the weight loss during combustion. Additionally, the theory was used to account for the process of rusting in metals.
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.
Who rejected phlogiston theory?
Antoine Lavoisier is credited with rejecting the phlogiston theory. Through his experiments and observations, he was able to show that combustion involved a process of oxidation rather than the release of phlogiston. This led to the development of modern chemistry.
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.

How did Antoine lavoisier disprove the phlogiston theory?
Antoine Lavoisier disproved the phlogiston theory by experimenting with combustion reactions and showing that burning substances gained weight instead of losing it. He demonstrated that oxygen is an essential component of combustion, not phlogiston as proposed by the theory. Lavoisier's precise measurements and meticulous approach to experimental evidence played a crucial role in discrediting the phlogiston theory and establishing the foundation for modern chemistry.
When iron rusts is it a phlogiston theory or a oxygen theory?
It is a process that involves oxygen. The phlogiston theory has been disprooven for a long time.

Was the phlogiston theory of burning correct?
No, it was not. The phenomena explained by the theory are now known to be a result of oxidation, and phlogiston does not exist.
Who propose the phlogiston theory?
The phlogiston theory was first proposed by Johann Joachim Becher in 1667. This theory is now considered obsolete and was replaced by the oxygen theory.

What is the principle of the phlogistan theory?
The phlogiston theory was a scientific hypothesis that proposed that all combustible materials contain a substance called "phlogiston," which is released during combustion. According to the theory, when a substance burns, it loses phlogiston. This theory has been disproven by modern chemistry.
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 good points of the phlogiston theory?
a combustible material is made up of 2 parts: the calx and phlogiston when a substance burnt the phlogiston into air and calx(ash) left behind so there are no good points of this theory
