As water is added to a 0.10 m nacl aqueous solution, the conductivity of the resulting solution

There are two types of conductance

a) molar conductance

b) specific conductance

specific conductance is also known as conductivity

Molar conductance [the conductance offered by one mole of electrolyte dissolved in any volume of solution] increases with increase in dilution. The reason for weak and strong electrolytes are different.

i) for weak electrolytes the molar conductance increases due to increase in degree of dissociation

ii) for strong electrolytes the molar conductance increases due to decrease in inter ionic interactions

Conductivity (specific conductance) is the conductance offered by one unit volume of an electrolytic solution

The conductivity decreases with increase in dilution due to less number of ions per unit volume of solution.

so here the conductivity of resulting solution will decrease if water is added to a 0.10 M NaCl  solution
