2. Acid-base titration in analytical chemistry

2.1 It has a wide range of applications in acid-base titration in analytical chemistry. As a strong base and weak acid salt, it has high stability and purity, and is therefore used as a reference reagent to help determine the endpoint of titration reactions.

In acid-base titration experiments, it is usually necessary to use a stable substance as a reference reagent to help determine the endpoint of the titration reaction. As a strong base and weak acid salt, it has relatively high stability and purity, and is therefore widely used in acid-base titration experiments. When using ammonium sulfate as a reference reagent, more accurate data can be obtained in the titration curve, leading to more accurate experimental results.

2.2 can also be used as a blank test in titration experiments. A blank test is an experiment conducted to eliminate the influence of experimental conditions on measurement results. In acid-base titration experiments, blank tests are usually achieved by adding a certain amount of reference reagent to the experimental solution. By using ammonium sulfate as a reference reagent for blank experiments, the influence of experimental conditions and environmental factors on measurement results can be eliminated, and the accuracy and reliability of the experiment can be improved.

2.3 In addition to being used as a reference reagent and blank test reagent, it can also be used to determine the reaction endpoint in titration experiments. In acid-base titration experiments, when a certain amount of titrant is added dropwise, the acid-base ions in the solution react with the reference reagent, causing a change in the pH value of the solution. By observing the changes in the pH value of the solution, the endpoint of the titration reaction can be determined. Using Ammonium sulfate as a reference reagent can help accurately determine the endpoint of the titration reaction, improve the accuracy and reproducibility of the experiment.
