For example, the titration curve for the titration between oxalic acid (a weak acid) and sodium hydroxide (a strong base) is pictured. The equivalence point occurs between pH 8-10, indicating the solution is basic at the equivalence point and an indicator such as phenolphthalein would be appropriate.
A typical titration curve of a diprotic acid, oxalic acid, titrated with a strong base, sodium hydroxide.Both equivalence points are visible. Titrations are often recorded on graphs called titration curves, which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the ...
Oxalic acid is used by some beekeepers as a miticide against the parasitic varroa mite. [52] Dilute solutions (0.05–0.15 M) of oxalic acid can be used to remove iron from clays such as kaolinite to produce light-colored ceramics. [53] Oxalic acid can be used to clean minerals like many other acids. Two such examples are quartz crystals and ...
For example, acetic acid is a weak acid which has a = 1.75 x 10 −5. Its conjugate base is the acetate ion with K b = 10 −14 / K a = 5.7 x 10 −10 (from the relationship K a × K b = 10 −14 ), which certainly does not correspond to a strong base.
A calculated titration curve of oxalic acid titrated with a solution of sodium hydroxide. The experimental determination of pK a values is commonly performed by means of titrations, in a medium of high ionic strength and at constant temperature. [58] A typical procedure would be as follows.

Why is perfluorohexanoic acid bad? At baseline, perfluorohexanoic acid is a forever chemical. That means it can build up in the body, with Peaslee noting that perfluorohexanoic acid ...
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. This can be used for weak bases and strong bases. [8] An example of an acidimetric titration involving a strong base is as ...
