  2. Standard solution - Wikipedia

    en.wikipedia.org/wiki/Standard_solution

    In analytical chemistry, a standard solution (titrant or titrator) is a solution containing an accurately known concentration. Standard solutions are generally prepared by dissolving a solute of known mass into a solvent to a precise volume, or by diluting a solution of known concentration with more solvent. [ 1 ]

  3. Titration - Wikipedia

    en.wikipedia.org/wiki/Titration

    Titration (also known as titrimetry [1] and volumetric analysis) is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte (a substance to be analyzed). A reagent, termed the titrant or titrator, [2] is prepared as a standard solution of known concentration and volume.

  4. Primary standard - Wikipedia

    en.wikipedia.org/wiki/Primary_standard

    Some examples of primary standards for titration of solutions, based on their high purity, are provided: [4] Arsenic trioxide for making sodium arsenite solution for standardisation of sodium periodate solution (until Ph. Eur. 3, Appendix 2001 also for iodine and cerium(IV) sulfate solutions, since Ph. Eur. 4, 2002 standardised by sodium ...

  5. Acid–base titration - Wikipedia

    en.wikipedia.org/wiki/Acid–base_titration

    Titration of a standard solution using methyl orange indicator. Titrate is in Erlenmeyer flask, titrant is in burette. acid + base → salt + water. For example: HCl + NaOH → NaCl + H 2 O. Acidimetry is the specialized analytical use of acid-base titration to determine the concentration of a basic (alkaline) substance using standard acid.

  6. Karl Fischer titration - Wikipedia

    en.wikipedia.org/wiki/Karl_Fischer_titration

    The volumetric titration is based on the same principles as the coulometric titration, except that the anode solution above now is used as the titrant solution. The titrant consists of an alcohol (ROH), base (B), SO 2 and a known concentration of I 2. Pyridine has been used as the base in this case. One mole of I 2 is consumed for each mole of ...

  7. Iodometry - Wikipedia

    en.wikipedia.org/wiki/Iodometry

    The iodometric titration is a general method to determine the concentration of an oxidising agent in solution. In an iodometric titration, a starch solution is used as an indicator since it can absorb the I 2 that is released, visually indicating a positive iodine-starch test with a deep blue hue. This absorption will cause the solution to ...

  8. Permanganometry - Wikipedia

    en.wikipedia.org/wiki/Permanganometry

    It is a redox titration that involves the use of permanganates to measure the amount of analyte present in unknown chemical samples. [1] It involves two steps, namely the titration of the analyte with potassium permanganate solution and then the standardization of potassium permanganate solution with standard sodium oxalate solution. The ...

  9. Cerimetry - Wikipedia

    en.wikipedia.org/wiki/Cerimetry

    Cerimetry or cerimetric titration, also known as cerate oximetry, is a method of volumetric chemical analysis developed by Ion Atanasiu. It is a redox titration in which an iron(II)–1,10-phenanthroline complex color change indicates the end point. Ferroin can be reversibly discolored in its oxidized form upon titration with a Ce 4+ solution ...
