      What Are Ionic Compounds?

      An ionic compound is any compound in which an electrostatic force holds the ions together. Ionic compounds are made of positively charged particles that rest against negatively charged particles in order to balance out the two particles’ magnetic imbalance. They can be found in both solid and liquid states, although solid ionic compounds are poor

    • 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

    • Potassium Carbonate Dihydrate

      Potassium Carbonate Dihydrate

      Potassium carbonate dihydrate (K2CO3.2H2O) is a white chemical. Salt from potassium carbonate and water from the dihydrate are mixed into a deliquescent (wet salt). It is a strong alkaline solution that garners a variety of uses. The salt tastes like salt and alkaline material. Potassium carbonate dihydrate is generally used as a nutritional supplement in

    • 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.

    • What is FTIR Spectroscopy?

      What is FTIR Spectroscopy?

      FTIR spectroscopy (Fourier Transform Infrared Spectroscopy) is a technique that uses infrared light to observe properties of a solid, liquid, or gas. It is used in many different applications to measure the absorption, emission, and photo-conductivity of matter by shining a narrow beam of infrared light at the matter in various wavelengths and detecting how

    • What is Phosphorescence?

      What is Phosphorescence?

      Phosphorescence is an effect in which some chemicals re-emit light that they absorb. It is similar to fluorescence, except that the chemical reactions within phosphorescent materials happen less often, thus they take longer to emit light. Phosphorescent materials can be recharged by being exposed to light and may store light for several hours before it

    • 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 is Photoelectron Spectroscopy?

      What is Photoelectron Spectroscopy?

      Photoelectron spectroscopy is the study of energy and how it relates to matter in terms of absorption and production. Photoelectron spectroscopy observes both wavelengths and frequencies and is used to view the physical composition of chemicals and solids. It is used in both analytical and physical chemistry and astronomy in order to study an object’s

    • 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

    • 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
