  • Ion exchange
    Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex.
  • Reagent
    A reagent /riˈeɪdʒənt/ is a substance or compound added to a system to cause a chemical reaction, or added to see if a reaction occurs.
  • Separation process
    A separation is a method to achieve any phenomenon that converts a mixture of chemical substance into two or more distinct product mixtures, which may be referred to as mixture.
  • Chemometrics
    Chemometrics is the science of extracting information from chemical systems by data-driven means.
  • Methyl orange
    Methyl orange is a pH indicator frequently used in titrations because of its clear and distinct colour change.
  • PH
    In chemistry, pH (/piːˈeɪtʃ/) is a numeric scale used to specify the acidity or basicity of an aqueous solution.
  • Quantitative analysis (chemistry)
    In analytical chemistry, Quantitative Analysis is the determination of the absolute or relative abundance (often expressed as a concentration) of one, several or all particular substance(s) present in a sample.
  • Spectrometer
    In physics, a spectrometer is an apparatus to measure a spectrum.
  • Sudan I
    Sudan I (also commonly known as CI Solvent Yellow 14 and Solvent Orange R), is an organic compound, typically classified as an azo dye.
  • Bioassay
    Bioassay (commonly used shorthand for biological assay or assessment), or biological standardization is a type of scientific experiment.
  • Potassium tetraiodomercurate(II)
    Potassium tetraiodomercurate(II) is an inorganic compound consisting of potassium cations and the tetraiodomercurate(II) anion.
  • 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.
