Chem notes:
Acids – pH<7 turn blue litmus paper red
Bases – pH>7 turn red litmus paper blue
Bases are caustic and are use in many cleaning products
Acids are sour and corrosive and react with metals
Organic compounds have a carbon atom whereas almost all inorganic compounds don’t have a
carbon atom
While most inorganic compounds do not contain carbon, there are a few that do:


Carbon monoxide (CO) and carbon dioxide (CO2 ) and
compounds including carbonates (CO32- ) carbides and cyanides (CN- ) are not organic.
Organic compounds will include things like the nucleic acids, found in DNA, lipids and fatty acids
found in the cells of living organisms, proteins and enzymes that are necessary for cellular processes
to take place, and more.
Meanwhile, inorganic compounds include the salts, metals, and other elemental compounds, not
based in life.
