Question

Agno3 (aq.) was added to an aqueous kcl solution gradually and the conductivity of the solution was measured. The plot of conductance () versus the volume of agno 3 is

Answer 1

When AgNO₃ is added, ppt begin to form till the ionic product of AgCl that is greater Kcp, is reached.  After that Cl⁻ begin to precipitate in form of AgCl. At the same time, NO₃⁻ are added to the solution so the number of ions remain same in solution.  When further AgNO3⁻ is added, number of ions in solution increases, hence conductance too.

Answer 2

Pls check the attachment.

On addition to AgNO3, salt of AgCl is formed. This conitnues till Cl(-) ions are used up. So till here the conductivity doesn't change much. After this, when AgNO3 is further added, NO3(-) ions increase in the solution which no of ions increase in the solution and so conductivity increases.

Hope it helps.
