Double Replacement Reaction

Lab Summary

Using a titration, determine the amount of chloride ion in water samples.

 

Theory

Determine the amount of chloride ion in water samples. Through this investigation, students:

  • Are introduced to the process of dissolving.
  • Learn rules governing the solubility of ionic compounds in aqueous solutions.
  • Understand double replacement reactions. 
  • Become familiar with net ionic equations.
  • Are introduced to the method of analytical titration.

Method

Students conduct the following procedures:

  • Titrate known and unknown water samples, employing a double replacement reaction between silver nitrate and sodium chloride.
  • Calculate the concentration of chloride ion in the water samples.
