Conductance titration works on the principle of ohm's law. If we are to find the strength of a acid then we take that acid into a beaker and dip the electrode of conductometer into the acid solution. This measures the conductance of acid. Now, we titrate this acid solution against the base of known molarity, the conductance starts decreasing. This is due to the binding of H+ ions of acid with the OH- of Base until a point is reached where conductance is minimum. When we move forward the conductance starts increasing again. This is now due to the free ions of Base present in solution.
The conductance produced by an ion is proportional to its concentration (at constant temperature),

What are the type of conductometric titration?
types of conductometric titration: acid base titration complexometric titration replacement titration redox titration precipitation titration
What are complexometric titration method?
Direct titration, Indirect titration, back titration, replacement titration and so on
What is over-titration?
over titration is when too much titrant is added to the analyte in a titration procedure.
Which type of the analysis the titration is?
Titration is a method of chemical analysis; for example: - volumetry - potentiometric titration - amperometric titration - radiometric titration - Karl Fisher titration - spectrophotometric titaration - viscosimetric titration and other methods
How many tipes of titration?
There are various types of titration. It is dependent on the conditions used and the reactants and desired products. Some of them are acid-base titration, redox titration, colorimetric titration and thermometric titration.
Why is conductance G?
Conductance is an opposition of Resistance and it is denoted by G. It is given by the relationship G = 1/R . In past the unit of conductance was (mho) which is opposite to (ohm). But these days the unit of conductance is Siemens which is denoted by 'S'.
Will a fully charged new battery have a low conductance reading?
No it will have high conductance

Graph for the conductometric titration between a weak acid and a srong base?
Weak Acid with a Strong Base, e.g. acetic acid with NaOH: Initially the conductance is low due to the feeble ionization of acetic acid. On the addition of base, there is decrease in conductance not only due to the replacement of H+ by Na+ but also suppresses the dissociation of acetic acid due to common ion acetate. But very soon, the conductance increases on adding NaOH as NaOH neutralizes the un-dissociated CH3COOH to CH3COONa which is the strong electrolyte. This increase in conductance continues raise up to the equivalence point. The graph near the equivalence point is curved due the hydrolysis of salt CH3COONa. Beyond the equivalence point, conductance increases more rapidly with the addition of NaOH due to the highly conducting OH− ions
Why conductance is ignored in transmission lines?
Conductance is ignored in short circuit studies because the inductance of the line is the dominant value. Conductance may not be ignored in stability studies.
What is over-titration?
over titration is when too much titrant is added to the analyte in a titration procedure.
The si unit of conductance is?
The unit of electrical conductance is the mho.
Which type of the analysis the titration is?
Titration is a method of chemical analysis; for example: - volumetry - potentiometric titration - amperometric titration - radiometric titration - Karl Fisher titration - spectrophotometric titaration - viscosimetric titration and other methods
What is the use of conductance?
When referring to electrical conductance, it is used in the application of electricity to equipment. Electrical conductance measures the equipment's ability to conduct electrical charge. A practical application would be to decrease the resistance in an electrical circuit so that the conductance is higher and electricity flows more smoothly.

What is effect of dilution on conductance?
The conductance of a given conductor, C = La/l ..(i)\ L = l/Ra ..(ii)The resistance is expressed in units of ohm, the conductance has units of ohm-1 or mho.The conductance of solutions is also governed by the same relations. From (i), if l = 1,a = 1, the specific conductance L = C. That is,the specific conductance (L) is the conductance of the solution enclosed between two electrodes of 1 sq. cm area and 1 cm apart. when you dilute the solution the concentration decrease and the specific conductance also decreaseThe conductance of a solution depends upon the number of ions present and hence on the concentration. To compare the conductivity of different solutions, it is necessary to take the concentration of the solutions into consideration. It is done by using equivalentconductance, l.
