Non-Aqueous Titration
Non – Aqueous Titration – Theory: In a non-aqueous titration, the titrant and analyte are not dissolved in water. This method used to determine the concentration of an analyte in a non-aqueous solvent. The titrant and analyte mixed in a flask, and the endpoint is determined using a spectrophotometer.
Non-Aqueous Titration Theory Example
When a titration conducted using a non-aqueous solvent, the titrant and analyte molecules must able to dissolve in the solvent. The titration involves the addition of a known volume of titrant to a known volume of analyte. The endpoint of the titration reached when the analyte completely reacted with the titrant.
In order to calculate the concentration of the analyte in the sample, the volume of titrant used and the molarity of the titrant must known. The concentration of the analyte can be determined from the following equation:
Where Vt the volume of titrant used, M is the molarity of the titrant, and Va is the volume of analyte.
Types of Non-Aqueous Solvents Used in Non-Aqueous Titration
Non-aqueous titration a type of titration in which an organic solvent used to dissolve the analyte. The organic solvent can be a weak acid or a weak base. The titration performed in the presence of a strong acid or a strong base. The strong acid or strong base used to titrate the weak acid or weak base.
Advantages of Non-aqueous Titrations
Non-aqueous titration is a type of titration that uses a solvent other than water. This type of titration used to determine the concentration of an unknown substance in a sample. In order to perform a non-aqueous titration, the chemist must first determine the concentration of the titrant (the substance used to determine the concentration of the unknown substance). The titrant then added to the sample until the desired endpoint reached. The concentration of the unknown substance can then calculated by using the concentration of the titrant and the volume of titrant used..
Applications of Non-aqueous Titration
Non-aqueous titration can used to determine the concentration of an unknown acid or base in a non-aqueous solution. It can also used to determine the equivalence point of a reaction between an acid and a base in a non-aqueous solution.
Disadvantages of Non-aqueous Titration
There are a few disadvantages to using non-aqueous titration. One is that the results can be difficult to interpret, as the concentration of the titrant in the sample solution can be difficult to determine. Additionally, the titrant can be more expensive than an aqueous titrant, and some non-aqueous titrants can be toxic.
