The so-called titer determination or standardization of a volumetric solution used for titration is one of the most important preconditions for reliable and transparent titration results . Accurate and reliable titration results are only achievable when we work with the exact concentration of the volumetric solution.
What is the purpose 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 do we need standardization?
The standards ensure that goods or services produced in a specific industry come with consistent quality and are equivalent to other comparable products or services in the same industry. Standardization also helps in ensuring the safety, interoperability, and compatibility of goods produced.
Why do we standardize in titration?
Titration is an absolute method (or primary method), meaning it is of utmost importance to know the exact concentration of the titrant you are using for your results to be accurate and repeatable by other analysts . This is why you need to carry out a standardization.
What are the types of standardization in chemistry?
The most commonly used technique for the standardization of a solution is titration. For a standardization process, a standard solution is required as a reference. Standard solutions can be found in two types as primary standard solutions and secondary standard solutions .
What is mean by standardization in chemistry?
Standardization is the process of determining the exact concentration (molarity) of a solution . Titration is one type of analytical procedure often used in standardization. In a titration, an exact volume of one substance is reacted with a known amount of another substance.
What standardize means?
transitive verb. 1 : to bring into conformity with a standard especially in order to assure consistency and regularity trying to standardize testing procedures There ought to be a law standardizing the controls for hot and cold in hotel and motel showers.—
What is standardization and its advantages?
Rationalize different varieties of products . Decrease the volume of products in the store and also the manufacturer cost. Improve the management and design. Speed up the management of orders.
What is standardization example?
An example of standardization would be the generally accepted accounting principles (GAAP) to which all companies listed on U.S. stock exchanges must adhere. ... Standardization ensures that certain goods or performances are produced in the same way via set guidelines.
Is standardization a good thing?
In theory, it’s a good idea as it relates to consumer research . It certainly helps with efficiency (we’ll talk about that one another time ?). Researchers are happy when they can compare the results of several studies because things are done the same way.
What is the purpose of standardization of NaOH?
A KHP sample of known mass (and, therefore, known moles) can be titrated with the NaOH solution to determine very precisely the concentration of the NaOH . This procedure is called standardizing the NaOH solution. Once this concentration is determined, the NaOH solution can serve as a standard for further work.
Why do we standardize sodium thiosulphate solution?
Sodium thiosulphate solution is standardized against potassium dichromate in presence of hydrochloric acid and potassium iodide . ... The iodine formed in the reaction oxidizes sodium thiosulphate giving sodium tetrathionate ion and the end point is detected by starch solution.
How does pH affect titration?
If you’re doing acid-base titration, pH plays a big role. It is usually done to determine the concentration of a solution or the molarity . pH indicates the end point. If you’re using titration to prepare a soluble salt, it may affect purity of the product obtained.
What is indicator and how it works?
pH indicators detect the presence of H+ and OH- . They do this by reacting with H+ and OH-: they are themselves weak acids and bases. If an indicator is a weak acid and is coloured and its conjugate base has a different colour, deprotonation causes a colour change.
What does standardize a solution mean?
Standardizing a solution refers to the process of determining an unknown concentration of substance within a solution .
