Question

Why conductance of a solution does not become zero at end point?

Answer 1

Even though you are precipitating BaSO4 out of solution and making H2O from H and OH, and thus losing ions from solution, conductivity won't go all the way to zero because plain water, even though it has low conductivity, does not have zero conductivity. (plain water at pH 7 has some H and OH ions still.)

Answer 2

Answer:

Even though it has a low conductivity, plain water nevertheless has conductivity. There are still some H and OH ions in ordinary water at pH 7.

Explanation:

• The characteristic of an electrolyte solution that aids in the conductivity of electricity in the solution is called conductance or electrical conductance (G = 1/R).
• The SI units of conductance in chemistry and physics are the ohm-1, mho, and siemens.
• A solution's conductance is influenced by its ion concentration and dilution. both the solute's and the solvent's natures.
• For instance, the conductance of the solution increases and the quantity of ions in the solution grows as the dilution level is increased.

Neutral water does have some protons and hydroxide ions left at the end point and this is why the conductance of a solution does not become zero.
