AgNO_(3(aq) was added to an aqueous KCl solution gradully and the conductivity of the solution was measured. The plot of conductance (Lambda) versus the volume of AgNO_(3) is |

Answer» `underset(("White ppt"))(AgNO_(3)(aq))+KCl(aq) to AgCl(s)+KNO_(3(aq))` `Ag^(+)(aq)+NO_(3)^(-)(aq)+K^(+)(aq)+Cl^(-)(aq) to AgCl(s)+K^(+)(aq)+NO_(3)^(-)(aq)` In this titration, known as conductometric litration, initially the conductance of the solution does not change much because the `Cl^(-)` ions are getting precipitated as AgCl and are replaced by `NO_(3)^(-)` ions Both the ions have nearly the same ionic conductnace Once the precipitation reaction is complete, the further ADDITION of `AgNO_(3)` will increase the concentration of `NO_(3)^(-)`ions in the solution. As a result, the conductance of solution will increase sharply as shown in the curve(s). |
