    • What is Flocculation?

      What is Flocculation?

      Flocculation is when microscopic particles bind together to form larger particles in liquids. It occurs naturally or artificially in water as well as other solutions. Flocculation is used in applications such as water purification, sewage treatment, cheese production, and brewing. It is also used in surface and physical chemistry, biology, and civil engineering. The term

    • Potassium Perchlorate

      Potassium Perchlorate

      Potassium Perchlorate (Potassium Chlorate (VII), perchloric acid, potassium salt, peroidin, and KClO4) is an inorganic salt that is used as a strong oxidizer. The function of potassium perchlorate’s oxidizer trait really depends on the chemical use. Potassium Perchlorate can be found in the following common items: Fireworks – Fireworks have many chemical compounds inside them,

    • What is a Plasma Cutter?

      What is a Plasma Cutter?

      A plasma cutter is a device that directs an ionized gas at an object under extreme temperatures. Plasma cutters are often used for industrial purposes, such as cutting metal, and are dependent on plasma, an extremely hot state of matter. Plasma cutters are essentially a type of plasma torch meant for cutting metal rather than

    • Mannitol Salt Agar

      Mannitol Salt Agar

      In order to grow a bacterial culture in a lab, a growth medium has to be used to provide the right environment. Mannitol salt agar is a popular bacterial growth medium that biologists use to grow halphile bacteria (these grow fast in high salt concentrations) and can tell the difference between non-pathogenic and pathogenic Staphylococcus

    • How is Chemical Energy Used

      How is Chemical Energy Used

      There are many different kinds of energy but the single most widely used in society as well as in nature is chemical energy. Chemical energy allows energy to be stored for later use and it is also easy to access. Without chemical energy, many of the luxuries and even basic necessities that people have grown

    • What is an Acetylene Torch?

      What is an Acetylene Torch?

      Acetylene is a hydrocarbon compound and is the simplest form of alkyne. Acetylene is colorless and extremely unstable in its pure form, which is why it is almost always mixed with other chemicals and handled as a solution. Acetylene was once the preferred gas in welding/cutting applications due to its ability to reach extremely high

    • Brookfield Viscometer

      Brookfield Viscometer

      The Brookfield Viscometer makes it possible to measure viscosity by employing techniques in viscometry. Viscometers (which can also be called viscosimeters) can measure viscosity through the varying flow conditions of the sample material being tested. They employ a spindle on a shaft that is designed to be dipped or immersed into a liquid that is

    • What Causes Copper to Turn Green?

      What Causes Copper to Turn Green?

      Copper turns green because of a process known as oxidation which is the removal of electrons from the substance. Specifically, copper turns green because of something known as copper carbonate. This is the substance that is found on top of copper–whether they be copper pipes, pennies, statues or anything else. So, the cause of copper

    • Methyl Iodide

      Methyl Iodide

      Methyl Iodide is a chemical compound that is relatively volatile. It is commonly found in the form of a dense, colorless liquid. It is also known as iodomethane and has the chemical formula CH3I (one carbon atom with three hydrogen atoms and a single iodine atom connected to it). Methyl iodide is a naturally occurring

    • What Are Pennies Made Of?

      What Are Pennies Made Of?

      Before 1982, the penny was made of copper which is why they, unlike most other coins, don't look silver. However, after 1982, the U.S. government realized that it was too expensive to make a penny–more than the penny was worth in money–so they decided, instead, to make it with a mixture of two different metals.
