Acid / Base analysis techniques in industries

  • Quantitative analysis of different types of precipitation is an important aspect in environmental studies. Measurement of acidity or basicity in snow or rainfall can be done by general titration methods.
  • Analysis of water to determine whether is safe or not is done by specialized titration instruments that measure the content of different chemical entities in a water sample and determines whether it is safe for intake.
  • Analysis of chemical substances in food products is an important phase to specify nutritional values. This step is carried out by a standard titration process that involves insertion of an electrode in the sample (for example orange juice) along with deionized water and then addition of titrant catalyst.
  • Simple titration kits are used by winemakers to understand the degree of acidity present in the wine.
  • Variant number of titration techniques using specialized instruments are used in pharmaceutical industries to ensure quality control.

Acid / Base analysis techniques by Aboriginal and Torres Strait Islander Peoples

  • The use of Bush Medicine was originated among the Aboriginal population and thus they knew how to remove toxicity from different materials that were later used as a form of medicine.
  • Aboriginal and Torres Strait Islander peoples used their organic and inorganic chemistry knowledge to form and utilise new substances, for example, quicklime (calcium oxide), pigments (iron oxide, charcoal), acid (pyroligneous acid), plaster (calcium sulphate), alkali salts (salts of potassium and sodium), beverages (ethanol), charcoal, and by-products such as heat and light.

Acid / Base analysis using digital probes and instruments

  • With the progression of technology, modern instruments have been introduced to carry out acid base analysis, which give more precise result as compared to the manual process.
  • Automatic Titrators are a range of microprocessor controlled titration equipment that are affordable and deliver endpoint detection based on data, minimizes sample usage and provides data accuracy which can be monitored in a computer or can be printed.
  • An automated Karl Fischer Titrator user the principles of coulometric or volumetric titration to determine trace amounts of water in a sample.
  • Potentiometric Titrators use a technique similar to direct titration of a redox reaction and is a useful means of characterizing an acid without the need of indicators and measuring the potential across the analyte.
