How does the conductometer work?
A conductometer measures the electrical conductivity of a solution by passing a small electric current through it and measuring the resulting resistance. The conductivity of the solution is directly proportional to the concentration of ions present in the solution, making it a useful tool for determining the purity of water and monitoring chemical reactions.
Does the conductometer directly measure the conductance of the solution or it measures individual ion conductance and then sum up?
it directly measures...
What is principle of conductometer?
The principle of a conductometer is based on measuring the electrical conductivity of a solution. It typically involves passing an electric current through the solution and measuring the resulting conductance to determine the concentration of ions present in the solution. Conductometers are commonly used in the field of analytical chemistry to measure the conductivity of a wide range of solutions.
How is conductometer works?
A conductometer measures the electrical conductivity of ionic solutions. This is done by applying an electric field between two electrodes. The ions wander in this field. The anions migrate to the anode and the cations to the cathode. In order to avoid substance conversions and the formation of diffusion layers at the electrodes (polarization), work is carried out with alternating voltage

What is conductance titration?
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),
