What does it mean to standardize HCl?
Standardization is the process of determining the exact concentration (molarity) of a solution. In the second procedure the standardized NaOH will be used to determine the molarity of a hydrochloric solution (HCl).
Why do we need to standardize both NaOH and HCl solution?
Solid NaOH is very hygroscopic and contains many impurities. It is also difficult to measure out concentrated HCl with any accuracy. Then, with our standardized NaOH solution, we can both determine the purity of an impure sample of KHP and titrate the HCl solution to accurately determine the HCl concentration.
What is the purpose of doing standardization?
The goal of standardization is to enforce a level of consistency or uniformity to certain practices or operations within the selected environment. An example of standardization would be the generally accepted accounting principles (GAAP) to which all companies listed on U.S. stock exchanges must adhere.
What is used to Standardise HCl?
Laboratory grade hydrochloric acid is not sufficiently pure to be used as a primary standard. In this experiment, a standard solution of sodium carbonate is used to determine the exact concentration of a hydrochloric acid solution.
How do you standardize HCl?
Preparation and Standardization of 0.1 M Hydrochloric acid (HCl)
- Take about 100 ml of water in a cleaned and dried 1000 ml volumetric flask.
- Add about 8.5 ml of Conc.
- Add more about 700 ml of water, mix and allow to cool to room temperature.
- Make up the volume 1000 ml with water.
What does it mean to standardize a solution?
Standardizing a solution refers to the process of determining an unknown concentration of substance within a solution.
Why HCl is not primary standard?
Primary Standards for Acid-Base Titrations Hydrochloric acid, HCl, and sulfuric acid, H2SO4, are NOT suitable for use as a primary standard because although they are both commercially available as concentrated solutions that are easily diluted, the concentration of the “concentrated” solution is NOT accurately known.
Why is it useful to Standardise a solution in computer science?
Standardizing on a solution allows IT teams to monitor and maintain the company’s programs and processes in a more organized, effective way.
What is the significance of standardization in chemistry?
Standardization determines the exact concentration of a solution. Standardization uses titration as in titration exact volume of one substance react…
Why is Standardisation carried out in chemistry?
Standardization is used to determine the exact concentration of a prepared solution. Titrations are used to determine the unknown concentrations of samples. Most often, standardization is also done as a titration.
Why HCl is a secondary standard?
A HCl solution is used as it can be prepared accurately and is quite stable. Because of this stability it is called a secondary standard. Even more accurate and stable standards are called primary standards.
