      Acrylic Adhesives

      An acrylic adhesive is a resin-based adhesive that is comprised of acrylic or methylacrylic polymers. It is rather complicated to produce acrylic adhesives as they must be formed into a polymer, suspended in a catalyst, and cured. Acrylic adhesives are very strong and efficient at bonding multiple objects together. They are resistant to sunlight, not

    • 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

    • Potassium Dichromate

      Potassium Dichromate

      Potassium dichromate (K2Cr2O7) is an inorganic chemical reagent that is normally used as an oxidizer in industrial and laboratory applications. It is used to oxidize alcohols and convert primary alcohols to aldehydes and sometimes carboxylic acids. Unlike similar processes that use permanganate, only carboxylic acids result. The secondary alcohols are converted into ketones and no

    • 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 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

    • Adhesive Removers

      Adhesive Removers

      An adhesive remover is a chemical that can break the chemical bonds of adhesives. There is a wide variety of adhesive removers because there are many different types of adhesives. Each adhesive on the market has a slightly different formula/chemical structure. Therefore, an adhesive remover must be specifically formulated to break down each adhesive. Adhesive

    • ESR Spectroscopy

      ESR Spectroscopy

      ESR Spectroscopy (Electron Spin Resonance Spectroscopy or Electron Paramagnetic Resonance Spectroscopy) is a technique used for studying chemical species that have one or more “free radical” or unpaired electrons. Most stable molecules only have paired electrons without any free radicals, so ESR Spectroscopy is used less often than NMR (Nuclear Magnetic Resonance) Spectroscopy, the usual

    • 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

    • Molality


      Molality is the number of moles in a solute per kilogram of solvent. It is often confused with the term molarity, which is an alternative unit for concentration that measures the number of moles of solute per liter of solution. Molality is commonly used when experiments require significant temperature changes. This is because a solute’s

    • 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,
