What is the practical use of titration?
Titration is an analytical technique that is widely used in the food industry. It allows food manufacturers to determine the quantity of a reactant in a sample. For example, it can be used to discover the amount of salt or sugar in a product or the concentration of vitamin C or E, which has an effect on product colour.
How do you write a practical titration?
Method
- Use a pipette and pipette filler to add 25 cm 3 of alkali solution to a clean conical flask.
- Add a few drops of a suitable indicator and put the conical flask on a white tile.
- Fill the burette with dilute acid.
- Slowly add the acid from the burette to the conical flask, swirling to mix.
How are titration questions calculated?
- Volume of sodium hydroxide solution = 25.00 ÷ 1000 = 0.0250 dm 3
- Amount of sodium hydroxide = 0.200 × 0.0250 = 0.005 mol.
- From the equation, 0.005 mol of NaOH reacts with 0.005 mol of HCl.
- Volume of hydrochloric acid = 22.70 ÷ 1000 = 0.0227 dm 3
- Concentration of hydrochloric acid = 0.005 mol ÷ 0.0227.
- = 0.220 mol/dm 3
What is titration chemistry?
A titration is defined as ‘the process of determining the quantity of a substance A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalence is achieved (the equivalence point)’.
Why are titrations used?
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Knowing the volume of titrant added allows the determination of the concentration of the unknown. Often, an indicator is used to usually signal the end of the reaction, the endpoint.
Where is titration used in real life?
Food Industry Uses Titration can be used to define oils, fats and similar substances. Specific titration procedures exist to test free fatty acid content, unsaturated fatty acids and trace amounts of water 2. Titration is also used to determine the estimated chain length of fatty acids in a fat.
What indicators can be used in titration?
Acid–base titration
Indicator | Color on acidic side | Color on basic side |
---|---|---|
Methyl red | Red | Yellow |
Litmus | Red | Blue |
Bromothymol blue | Yellow | Blue |
Phenolphthalein | Colorless | Pink |

Is titration qualitative or quantitative?
Titration, also known as titrimetry, is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte (Medwick and Kirschner, 2010). Since volume measurements play a key role in titration, it is also known as volumetric analysis.
What are the steps to titration?
Following are the steps to complete a titration test: Measure 1 gram of lye on a scale. Measure 1 liter of distilled water into a beaker. Thoroughly mix the gram of lye with the liter of water until it’s dissolved. Measure 10 milliliters of isopropyl alcohol into a separate beaker. Thoroughly mix 1 milliliter of used vegetable oil into the alcohol.
What is a practical application of titration?
Other uses of titration in the food industry include tests for the amount of salt or sugar, and the concentration of vitamin C or E, in a product. Titration is also used in wine and cheese production to test the product’s readiness for consumption.
What are the precaution steps for titration?
Always add acid to water not water to acid. Same goes for basic reagents.
What is the process of a titration?
Titration, process of chemical analysis in which the quantity of some constituent of a sample is determined by adding to the measured sample an exactly known quantity of another substance with which the desired constituent reacts in a definite, known proportion. The process is usually carried out by gradually adding…
