What is the aim of Conductometry?
Conductometry is often applied to determine the total conductance of a solution or to analyze the end point of titrations that include ions.
What is Conductometry technique?
The conductometric method measures the ability of an analyte or medium to conduct an electrical current between electrodes or reference nodes.
What are the types of Conductometry?
Types of conductometric titrations:
- Acid-base titration.
- Precipitation titration.
- Replacement titration.
- Redox (oxidation-reduction) titration.
- Complexometric titration.
What are the principles of conductometric experiment?
The principle of conductometric titration is based on the fact that during the titration, one of the ions is replaced by the other and invariably these two ions differ in the ionic conductivity with the result that conductivity of the solution varies during the course of titration.
Which cell is used in Conductometry?
The two electrode cell is the most commonly used conductivity cell Glass cells have electrodes made of platinum….Conductivity Cells.
Water | uS/cm |
---|---|
Surface water | 30 – 7000 |
Waste water | 700 – 7000 |
Brackish water | 1000 – 8000 |
Ocean water | 40000 – 55000 |
What are the applications of conductometric measurement?
Conductometric titrations are used to determine water purity. It is used to check the levels of pollution present in different small water bodies like lakes, ponds or rivers. Conductometry can also be used to examine the salinity of seawater and the alkalinity of freshwater or freshwater bodies.
What is the disadvantage of using conductometric analysis?
Limitations of Conductometric Titration By conductometric titration technique, only a few specific redox titrations can be carried out. It shows less accurate results when the total electrolytic concentration is high in solution. It makes it less satisfactory.
What is Conductometry PPT?
It is an electrochemical method of analysis used for the determination or measurement of the electrical conductance of an electrolyte solution by means of a conductometer. Electric conductivity of an electrolyte solution depends on : Type of ions (cations, anions, singly or doubly charged.
On what factors conductance depends?
(1) Nature of electrolyte: The conductance of an electrolyte depends upon the number of ions present in the solution. Therefore, the greater the number of ions in the solution the greater is the conductance. The number of ions produced by an electrolyte depends upon its nature.
How many electrodes are used in Conductometry?
Conductometry is a process in which two electrodes are used to measure all electroactive compounds in a solution. In this, Platinum sheets are used. Each sheet is fixed at 1cm distance.
Where is conductivity used?
Conductivity measurement is widely used for quality control purposes. For monitoring and controlling of used water, conductivity is one of the important, cost-effective and stable parameter. That is the reason conductivity measurement has found numerous industrial applications.
What is conductivity cell in Conductometry?
• It is an electrochemical method of analysis concerned with. electrical conductance through an electrolyte solution . ( or) It is defined has as determination or measurement of the electrical conductance of an electrolyte solution by means of a conductometer .
What is the difference between conductance and conductivity?
Conductance is the extrinsic property, whereas the inherent property is conductivity. This suggests that conductance is an object’s property depending on its quantity/mass or physical form and scale, whereas conductivity is the object’s intrinsic property of the substance.
Which cell is used in conductometer?
How is conductivity used in real life?
Conductivity can also be used to monitor nutrient concentrations in liquid fertilizers. A quick check of the conductivity of liquid fertilizers can guard against mistakes such as improper mixing or malfunctioning injectors, protecting crops from wasteful over-fertilization or inadequate fertilizer application.
What are examples of conductivity?
An example of conductivity is heat transferring from hot pot of soup to a metal ladle sitting in the pot. The ability or power to conduct or transmit heat, electricity, or sound. The conductance of a material. The ability of a material to conduct electricity, heat, fluid or sound.
What is Conductometry Slideshare?
It is an electrochemical method of analysis used for the determination or measurement of the electrical conductance of an electrolyte solution by means of a conductometer. Electric conductivity of an electrolyte solution depends on : Type of ions (cations, anions, singly or doubly charged. Concentration of ions.
What is conductometry in chemistry?
Look up conductometry in Wiktionary, the free dictionary. Conductometry is a measurement of electrolytic conductivity to monitor a progress of chemical reaction. Conductometry has notable application in analytical chemistry, where conductometric titration is a standard technique.
What is the history of conductometry?
Friedrich Kohlrausch further developed conductometry in the 1860s when he applied alternating current to water, acids, and other solutions. It was also around this time when Willis Whitney, who was studying the interactions of sulfuric acid and chromium sulfate complexes, found the first conductometric endpoint.
What is conductometric analysis of electrolytes?
Conductometric analysis of electrolytes is a long-time practice. Henry Cavendish and Andreas Baumgartner reported the analysis of mineral waters and salt solutions by using conductometric methods. Georg Quincke and Emil Warburg checked the water solubility of glasses.
What is the significance of the glass electrode in conductometry?
This development allowed for testing the solubility of salts and hydrogen ion concentration, as well as acid/base and redox titrations. Conductometry was further improved with the development of the glass electrode, which began in 1909.
