Analysis of Gravimetric Analysis Titration

Gravimetric Analysis Titration is a common laboratory technique used to determine the concentration of an analyte in a sample. In this process, a known volume of titrant is given and mixed with the sample until the required endpoint is reached. The amount or volume of the analyte can then be found using this information. In this blog post, we will provide a brief overview of Gravimetric Analysis Titration and discuss some of its key steps and components.

What is Gravimetric Analysis?

Gravimetric analysis is a type of analytical procedure where the amount of an analyte which is an ion is determined by weighing the precipitate that is formed by the reaction of the analyte with another reagent.

The Objective of the Gravimetric Analysis

The underlying cause behind gravimetric analysis is the measurement of the mass or volume of an analyte based on its weight. The principle is widely used in many industries including the food and beverage industry, where it is used to determine the fat content of products. In the medical field, gravimetric analysis is used to measure the number of drugs in a patient’s blood.

Types of Gravimetric Analysis

There are four types of gravimetric analysis including the precipitation gravimetric,  the adsorption gravimetric, the complexation gravimetric, and the electrochemical gravimetric.

Precipitation Gravimetric:  In this method, the analyte is precipitated out of the solution and then weighed. In this process, the excess oxalic acid is added to the solution which will then precipitate the calcium ions. The calcium oxalate is then filtered, dried and weighed to get the gravimetric factor.

Adsorption Gravimetric: This method is used when the analyte has a low concentration. In this process, the ion-exchange resin is used to adsorb the analyte. The ion-exchange resin will then be washed and dried before being weighed to get the gravimetric factor.

Complexation Gravimetric: This method is used when the analyte is complexed with a reagent. The complex is then precipitated and weighed to get the gravimetric factor.

Electrochemical Gravimetric: This method is used when the analyte is an electrode. The current is then measured to get the gravimetric factor.

Gravimetric Analysis Steps

There are four main steps in gravimetric analysis:

– Sample collection:  The first step is to collect the sample that you will be analyzing. This can be done in a variety of ways, depending on the type of sample you are collecting.

– Sample preparation: Once the sample is collected, it must be prepared for analysis. This usually involves drying the sample and crushing it into a powder.

– Analysis: The next step is to actually perform the gravimetric analysis. This involves weighing the sample and then determining the percentage of the sample that is made up of the desired element.

– Data interpretation: The final step is to interpret the data from the analysis. This can be done in a number of ways, depending on the type of data you have collected.

Gravimetric analysis is a powerful tool that can be used to determine the composition of a sample. By following the steps above, you can ensure that your gravimetric analysis is carried out correctly and that you get accurate results.

Advantages and Disadvantages of Gravimetric Analysis

Advantages of Gravimetric Analysis:

-It is a very precise method of analysis.

-It can be used to determine the purity of a substance.

-It can be used to determine the composition of a mixture.

Disadvantages of Gravimetric Analysis:

-It is a time-consuming method of analysis.

-It requires the use of expensive equipment.

-It is a difficult method of analysis to master.

Despite the disadvantages, gravimetric analysis is still widely used in many industries because it is a very reliable method of analysis. It is important to remember that gravimetric analysis is just one tool that can be used to analyse a substance; there are many other methods of analysis that can complement gravimetric analysis.

Conclusion

The method where the required amount of titrant is mixed to reach the endpoint as per the need is called Gravimetric analysis and it is a highly accurate and precise method for the determination of an analyte’s concentration. This method can be used in a wide variety of industries and applications. When choosing a gravimetric analysis method, it is important to consider the sample size, analyte concentration, and desired precision and accuracy. With the proper method selection and execution, gravimetric analysis can provide reliable results. In this article, we dealt with the basics of gravimetric analysis including titration.
