Question

What is the principle of assay of Sodium bicarbonate

Redox titration
Complexometric titration
Arginometric titration
Neutralization titration​

Answer 1

Answer:

a bicarbonate assay it just a determination of how much bicarbonate is in the solution, which is commonly done by a titration.. Assay Weigh accurately about 0.6 g ofSodium Carbonate, previously dried, dissolve in 50 ml of water, and titrate with 0.5 mol/l hydrochloric acid (indicator: 3 drops of bromophenol blue TS).

1.Redox Titration is a laboratory method of determining the concentration of a given analyte by causing a redox reaction between the titrant and the analyte. These types of titrations sometimes require the use of a potentiometer or a redox indicator.

2.Complexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution.

3.The titrations with silver nitrate are known as argentometric titration. This titration is carried out for chloride, cyanide, and bromide ions

4.The equivalence point of a neutralization reaction is when both the acid and the base in the reaction have been completely consumed and neither of them are in excess. When a strong acid neutralizes a weak base, the resulting solution's pH will be less than 7.
