Concept explainers
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 L of 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 BaCl2 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.

Concept introduction:
Precipitation reaction:
- If precipitate is formed, when two solutions are mixed together is called precipitation reaction.
- The amount of precipitate formed is related to the amount of reactants taken in to the reaction.
Neutralization reaction:
- The reaction between acid and base to gives a salt is the known as neutralization reaction.
Strong and weak electrolytes:
- The compound dissolved in water and completely dissociates to produces the ions is known as strong electrolytes.
- The compound dissolved in water but not completely dissociates to produces the ions is known as strong electrolytes.
Electrical conductivity of electrolytes:
- The strong electrolytes are having high electrical conductivity than weak electrolytes.
- The number of ion in solution is directly proportional to the electrical conductivity of electrolytes.
Conductivity titration:
- The measurement of electrical conductivity of titration mixture to gives a end point if the reaction.
- The sudden change in the slope is a equivalent point of the titration and it is the end point.
