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 is the difference between specific conductance and equivalence conductance?
Specific conductance is the conductance of a specified length of a substance, typically 1 cm, while equivalence conductance is the conductance of all ions produced by one mole of an electrolyte in solution. Specific conductance is a property of the substance itself, whereas equivalence conductance is a property of the electrolyte in solution.
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 do conductance increases after the end point in conductometric titrations?
Conductance can increase after the end point in conductometric titrations due to the presence of excess titrant in the solution, leading to higher conductivity. This excess titrant can contribute to the conductance of the solution and cause an increase in measured conductance. Factors such as incomplete reaction or side reactions can also contribute to the increase in conductance post-end point.
What is over-titration?
Over-titration refers to the process of adding too much titrant during a titration, resulting in an endpoint that goes beyond the equivalence point. This can lead to inaccurate results as the excess titrant can skew the calculations.
What is the scout titration?
The scout titration is a preliminary titration carried out to estimate the approximate endpoint in a titration experiment before performing the actual titration. It helps in determining the approximate volume of titrant required for the main titration to avoid overshooting the endpoint.
Why conductance is increased after the end point in conductometric titration?
In conductometric titration, conductance increases after the endpoint because, beyond this point, excess titrant ions enter the solution, contributing to a higher ionic concentration. As the reaction between the titrant and analyte is complete, the remaining titrant ions, which are typically more conductive than the analyte ions, dominate the solution's conductivity. This results in a measurable increase in conductance, indicating that the titration has surpassed the equivalence point.
What is the difference between specific conductance and equivalence conductance?
Specific conductance is the conductance of a specified length of a substance, typically 1 cm, while equivalence conductance is the conductance of all ions produced by one mole of an electrolyte in solution. Specific conductance is a property of the substance itself, whereas equivalence conductance is a property of the electrolyte in solution.
How are specific conductance and equivalent conductance related to concentration of electrolyte?
Specific conductance is directly proportional to the concentration of electrolyte, while equivalent conductance is inversely proportional to the concentration of electrolyte. This is because specific conductance is the conductivity of a solution normalized to a unit concentration, while equivalent conductance is the conductivity of a solution containing one equivalent of the electrolyte.
What happens to the current if the conductance decreases?
If conductance decreases, the current flowing through the circuit will also decrease. Conductance is the inverse of resistance, so decreasing conductance means increasing resistance, which impedes the flow of current.
Will a fully charged new battery have a low conductance reading?
No it will have high conductance
Why you caluculate the corrected conductance?
Corrected conductance is calculated to account for the impact of temperature on the conductance of a substance. Conductance is temperature-dependent, so correcting for this allows for a more accurate comparison of values across different temperatures. It helps to standardize conductance measurements and make them more reliable for analysis.
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.
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.
What is the conductance of a wire that has a resistance of 400 ohms?
The conductance of a wire is the reciprocal of its resistance. Therefore, for a wire with a resistance of 400 ohms, the conductance would be 1/400 siemens, or 0.0025 siemens.
Why do conductance increases after the end point in conductometric titrations?
Conductance can increase after the end point in conductometric titrations due to the presence of excess titrant in the solution, leading to higher conductivity. This excess titrant can contribute to the conductance of the solution and cause an increase in measured conductance. Factors such as incomplete reaction or side reactions can also contribute to the increase in conductance post-end point.
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 over-titration?
Over-titration refers to the process of adding too much titrant during a titration, resulting in an endpoint that goes beyond the equivalence point. This can lead to inaccurate results as the excess titrant can skew the calculations.
