Methanol (CH3OH), also called methyl alcohol, wood alcohol, or wood spirit, the simplest of a long series of organic compounds called alcohols, consisting of a methyl group (CH3) linked with a hydroxy group (OH). Methanol was formerly produced by the destructive distillation of wood
Nitric acid, also known as aqua fortis and spirit of niter, is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water
What is Potassium Iodide (KI)? KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine
Formaldehyde is a gas that is dissolved in water to form the compound formalin. Formalin is the saturated solution of formaldehyde in water. A 100% formalin solution is equivalent to 37%–40% formaldehyde. In dialysis, a 4% formaldehyde (11% formalin) concentration is used
A conductivity meter measures the amount of electrical current or conductance in a solution. Conductivity is useful in determining the overall health of a natural water body
Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH3
Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid
Soil Hydrometers are used to test the particle size distribution of fine-grained soils in the hydrometer analysis of soils test. The hydrometers measure suspended solids in sedimentation cylinders over time periods of up to 24 hours
Silver nitrate is a natural compound that is used as an antiinfective agent. Silver nitrate topical (for use on the skin) is used to cauterize infected tissues around a skin wound. Silver nitrate can also help create a scab to help stop bleeding from a minor skin wound
Ethanol is an organic chemical compound. It is a simple alcohol with the chemical formula C2H6O. Its formula can be also written as CH 3−CH 2−OH or C 2H 5OH, and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste
Hydrochloric acid (HCl, also known as muriatic acid) is a colorless corrosive, strong mineral acid with many industrial uses among which, when it reacts with an organic base it forms a hydrochloride salt
Paper chromatography has become standard practice for the separation of complex mixtures of amino acids, peptides, carbohydrates, steroids, purines, and a long list of simple organic compounds. Inorganic ions can also readily be separated on paper
In biochemistry, the photoelectric colorimeter is commonly employed for measurement of different substances in the blood like glucose, blood urea, blood enzymes, and others. It is used for measuring the transmittance and absorbance of light passing through a liquid sample
