What is the principle of Conductometry?

What is the principle of Conductometry?

Principle of the conductometric titrations theory states that for dilutions that are infinite, ions act independently and in the process contribute toward conductance of the solution. The principle behind this theory states that anions and cations have different conductance values.

What is Conductometry used for?

Conductometry is used to analyze ionic species and to monitor a chemical reaction by studying the electrolytic conductivity of the reacting species or the resultant products.

What is the unit of Conductometry?

Conductometry is the measurement of the electrical conductivity of a solution. The conductance is defined as the current flow through the conductor. In other words, it is defined as the reciprocal of the resistance. The unit for the conductance is Seimens (S) which is the reciprocal of Ohm’s (Ω −1).

What is conductivity water?

Conductivity is a measure of water’s capability to pass electrical flow. This ability is directly related to the concentration of ions in the water 1. Compounds that dissolve into ions are also known as electrolytes 40. The more ions that are present, the higher the conductivity of water.

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 is Conductometry and application of Conductometry?

APPLICATION OF CONDUCTOMETRY :- Finding conductance of unknown compound. salt analysis. Ionic product of water. Determination of solubility and Ksp of sparingly soluble compound. Determination of mode of ionization of complex compound.

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. Concentration of ions.

Who limits water conductivity?

Generally, the amount of dissolved solids in water determines the electrical conductivity. Electrical conductivity (EC) actually measures the ionic process of a solution that enables it to transmit current. According to WHO standards, EC value should not exceeded 400 μS/cm.

What is conductometric cell?

A conductivity cell is a device that is comprised of electrodes that sense the electrical conductivity of a substance, such as water. Electrode size, the distance between each, and the pattern of the electrical field present determine this cell constant.

What is the definition of conductometry in chemistry?

Definition of conductometry. : determination of the quantity of a material (as an element or salt) present in a mixture by measurement of its effect on the electrical conductivity of the mixture.

What are the instruments used in conductometric determination?

Instrumentments used in conductometric determination To carry out conductometric measurement it is necessary to measure the resistance of the solution and the conductance is i/r. The instrument consists of two parts: A mean to measure the resistance and then converts it to conductivity unit this called conductivity bridge.

When do you use A.C in conductometry?

1. Always A.C is used to prevent polarization of electrode in conductivity. As the frequency of current increases, conductance increases. 2. Strong electrolytes have higher conductance. 3. 4. 5. Absolute velocity of any ion under influence of 1 volt potential per cm is called ionic mobility.

When is conductometry used as a synonym for titration?

Conductometry has notable application in analytical chemistry, where conductometric titration is a standard technique. In usual analytical chemistry practice, the term conductometry is used as a synonym of conductometric titration, while the term conductimetry is used to describe non-titrative applications.
