Methylene blue
Methylene blue (CI 52015), also known as methylthioninium chloride, has many uses in biology and chemistry; for example, it can be used as a stain and as a medication.
Acid dissociation constant
An acid dissociation constant, Ka, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution.
Neutron activation analysis
Neutron activation analysis (NAA) is a nuclear process used for determining the concentrations of elements in a vast amount of materials.
PH indicator
A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually.
Polarography
Polarography is a subclass of voltammetry where the working electrode is a dropping mercury electrode (DME) or a static mercury drop electrode (SMDE), which are useful for their wide cathodic ranges and renewable surfaces.
Eriochrome Black T
Eriochrome Black T is a complexometric indicator that is used in complexometric titrations, e.
Ultraviolet–visible spectroscopy
Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region.
Colorimetry (chemical method)
In physical and analytical chemistry, colorimetry or colourimetry is a technique "used to determine the concentration of colored compounds in solution.
X-ray spectroscopy
X-ray spectroscopy is a gathering name for several spectroscopic techniques for characterization of materials by using x-ray excitation.
Ferroin
Ferroin is the chemical compound with the formula [Fe(o-phen)3]SO4, where o-phen is an abbreviation for 1,10-phenanthroline, a bidentate ligand.
Devarda's alloy
Devarda's alloy (CAS # 8049-11-4), is an alloy of aluminium (44% – 46%), copper (49% – 51%) and zinc (4% – 6%).
Brilliant Green (dye)
Brilliant Green is one of the triarylmethane dyes.
Elution
In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions.
Salicylaldoxime
Salicylaldoxime is an organic compound described by the formula C6H4CH=NOH-2-OH.
Sample (material)
In general, a sample is a limited quantity of something which is intended to be similar to and represent a larger amount of that thing(s).
Water content
Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, fruit, or wood.
Para-Dimethylaminobenzaldehyde
para-Dimethylaminobenzaldehyde is an organic compound containing amine and aldehyde moieties which is used in Ehrlich's reagent and Kovac's reagent to test for indoles.
Rhodizonic acid
Rhodizonic acid is a chemical compound with formula C6H2O6 or (CO)4(COH)2.
Filter paper
Filter paper is a semi-permeable paper barrier placed perpendicular to a liquid or air flow.
Aluminon
Aluminon, the triammonium salt of aurintricarboxylic acid, is a dye commonly used to detect the presence of the aluminium ion in an aqueous solution.
Qualitative inorganic analysis
Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find elemental composition of inorganic compounds.
Quantification (science)
In mathematics and empirical science, quantification (or quantitation) is the act of counting and measuring that maps human sense observations and experiences into quantities.
Quality of analytical results
Quality of measurements made in chemistry and other areas is an important issue in today’s world as measurements influence quality of life, cross-border trade and commerce.
