Because the acid-base and precipitation reactions discussed in this chapter all involve ionic species, their progress can be monitored by measuring the electrical conductance of the solution. Match each of the following reactions with one of the diagrams shown here. The electrical conductance is shown in arbitrary units. Explain the significance of the point at which the slope changes in each diagram.

(1) A 1.0 M KOH solution is added to 1.0 Lof 1.0 M HC2H3O2.

(2) A 1.0 M NaOH solution is added to 1.0 L of 1.0 M HCl.

(3) A 1.0 M BaCl, solution is added to 1.0 L of 1.0 M K2SO4.

(4) A 1.0 M NaCl solution is added to 1.0 L of 1.0 M AgNO3.

(5) A 1.0 M HC2H3O2 solution is added to 1.0 L of 1.0 M NH3.
