CHEMISTRY
Did you know that chemistry is associated to
everyday activities of human?
 Fluoride in a toothpaste, that prevents tooth decay.
 Calcium carbide or Calcium acetylide, or termed as “Kalburo” is
used for ripening fruits. It produces acethylene.
 LPG in our gas tank is typically odorless (propane and butane),
the smell is from the other agent called Ethyl Mercaptan.
Chemistry History
3000 BC
• Chemistry is known as art not science.
1000 BC
• Smelting or extraction of metals from ore.
Pre-alchemy period
• Thales introduced conversion of substance from other substance.
Chemistry History
• Empedocer suggested the Four basic elements – air, water, fire and Earth.
• Aristotle suggested heavenly ether that is added to the 4 basic elements introduced
by Empedocer..
• Democritus suggested that matter is composed of atoms.
Chemistry History
4th BC to Middle
Ages
• Alchemy started. Paracelsus is a common alchemist.
Modern Chemistry
• Idea of chemical investigation
Mid- 17th Century
• Johann Joachim Becher and Georg Ernst Stahl introduced theory of Phlogiston.
Chemistry History
• Joseph Priestly supported the Theory of Phlogiston and even do an experiment.
• Antoine Lavoisier suggested that oxygen gas is absorbed from the air instead of
phlogiston.
What is Chemistry?
 It deals with the study of matter, its composition, its properties, changes it
undergoes, and the energy associated with these changes.
 It is connected to other field of Science – Biology, pharmacology, Geology,
Astronomy, Physiology, Medicine, Meteorology, electronics, Ecology,
Psychology, Metallurgy, Engineering, Toxicology, and Physics.
Investigatory Process
 Studying science is based on making keen
observations and formulating intelligence guesses
based on the observed phenomenon.
 It is also termed as Scientific Method.
