The concept of acid-base titration dates back to the late 18th century.
Swedish chemist, Carl Wilhelm Scheele, is credited with laying the groundwork for acid-base titration in His discoveries paved the way for the development of this crucial analytical technique.
Acid-base titration can be used to determine the pH of a solution.
By using an appropriate indicator or pH meter, the endpoint of the titration can be determined, allowing for the calculation of the pH of the analyte solution, providing valuable information about its acidity or basicity.
Acid-base titration is commonly used in the pharmaceutical industry.
Pharmaceutical companies rely on acid-base titration to ensure the quality and potency of their products. It is used in the analysis of drugs, determining their acid or base content, and verifying their concentration.
Acid-base titration can be used to perform a neutralization reaction.
When an acid and a base react in a 1:1 ratio, they undergo a neutralization reaction. Acid-base titration allows for the determination of the exact ratio required to achieve neutralization.
Titration curves are graphical representations of acid-base titration data.
Titration curves show the pH of the solution being titrated plotted against the volume of the titrant added. These curves provide valuable information about the nature of the acid or base being analyzed.
Acid-base titration can be used to determine the molar mass of an unknown substance.
Using the known concentration of the titrant and the volume required for neutralization, the molar mass of the analyte can be calculated. This is especially useful when working with non-volatile or thermally unstable substances.
Acid-base titration can be performed using different indicators.
Indicators such as phenolphthalein and bromothymol blue can be used to determine the endpoint of the titration. These indicators change color when the solution reaches a specific pH, helping to visually identify when neutralization has occurred.
Acid-base titration is an essential technique in environmental analysis.
Environmental scientists use acid-base titration to measure the acidity of natural water bodies. This technique helps monitor the environmental impact of pollution and assess the efficiency of water treatment processes.
