What are the principles of Conductometry?
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.
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.
Which is working principle of Conductometry measurement of conductivity?
The working principle of conductometric titration is measurement the conductivity of the solution. Conductometry is employed to investigate ionic species and to observe a reaction by studying the electrolytic conductivity of the reacting species or the resultant products.
What is Conductometry function?
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. It has notable applications in analytical chemistry.
Which electrode is used in Conductometry?
Answer: Conductivity cell :- Made of pyrex or quartz and are fitted with two platinum electrodes. Should be placed in vessel containing water to maintain constant temp. types of conductivity cells are TYPE-A, TYPE-B, & TYPE-C.
Which is application of Conductometry?
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.
Why KCl is used in Conductometry?
KCl is used for calibration of conductivity meter because it is very stable. EXPLANATION: KCl or potassium chloride is product of reaction between a strong acid and a strong base, so it is strongly bonded because of high electropositive nature of potassium and high electronegative nature of chlorine.
Which current is used in Conductometry?
alternating current (AC)
Solution : All conductance measurements are done by alternating current (AC) and not by direct current (DC). If DC is used, electrolysis will occur and concentration of the solution will change with time.
What is conductance formula?
Conductance is the opposite of resistance: the measure of how easy it is for electric current to flow through something. Conductance is symbolized with the letter “G” and is measured in units of mhos or Siemens. Mathematically, conductance equals the reciprocal of resistance: G = 1/R.
