1、There are three conditions in total.
(1) Analytical balances with accurate weighing substances and vessels measuring solution volume
(2) Standard solutions capable of titration
(3) Indicators for accurately determining the theoretical endpoint.
- Classification of titration analysis.
There are four categories, acid-base titration, complexometric titration, redox titration, and precipitation titration.
The acid-base titration method is a titration analysis method based on a proton transfer reaction using an acid and a base in water .
It can be used to determine acid, base and amphoteric substances. It is a method for capacity analysis using acid-base reaction. The acid can be used as a titrant to determine the base, and the base can be used as a titrant to determine the acid, which is an extremely versatile analytical method. The most commonly used acid standard solution is hydrochloric acid, sometimes with nitric acid and sulfuric acid. The reference material for which they are calibrated is sodium carbonate.
The complexometric titration method is a titration analysis method based on a complexation reaction . It mainly uses ammonia carboxylate complexing agent as a titrant. These amino carboxylate complexing agents have strong complexing ability to many metals.
Redox titration is a titration analysis method based on electron transfer between an oxidant and a reducing agent in a solution. And acid-base titration and ligand titration compared redox titration application is very wide, it can be used not only inorganic analysis, and can be widely used for organic analysis , having a number of oxidizing or reducing organic compound can be used a redox The titration method was used for the measurement.
precipitation titration is a titration analysis method based on precipitation reaction .
