What substance is produced during combustion and is often confused with ash?

Soot is produced during combustion and is often confused with ash because both substances can result from burning materials. During combustion, particularly incomplete combustion, carbon particles are released, which accumulate to form soot. Soot is a black, powdery substance composed mainly of carbon, and it can be found floating in the air as well as settling on surfaces, which leads to it being mistaken for ash.

Ash, on the other hand, is the inorganic residue left after combustion, comprised mainly of minerals that do not combust. While ash appears more like a fine powder, soot has a darker appearance due to its carbon content.

Understanding the difference between these products of combustion is essential in fields such as environmental science and combustion engineering, as soot can have significant implications for air quality and health.
