Purple is defined as a deep, rich shade between crimson and violet, or, more broadly, as a range of hues of color between blue and red, or as a dark color that is a blend of red and blue.
Dry ice is the solid form of carbon dioxide (CO2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, non-flammable, with a sour zesty odor, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H2CO3).
A. Dry ice is frozen carbon dioxide. It will keep perishable foods colder and longer than traditional ice. It is an excellent refrigerant for shipping, camping and bulk use. Unlike traditional ice that melts into water, dry ice turns into a gas appearing like fog or steam.. Ice should be clear in color as well as odorless and tasteless. When purchasing ice, look for bags that are properly closed and secure (no drawstring ties). The bag should carry the manufacturerâs name and address. Also look for the International Packaged Ice Associaton (IPIA) symbol.
