Editing Properties Of Solutions Electrolytes And Non - Electrolytes

ApchemWiki | RecentChanges | Preferences

*Introduction 
This lab introduces you to the properties of strong and weak electrolytes and non-electrolyte solutions. An electrolyte is a material that dissolves in water to give a solution that conducts an electric current. To carry this current, an electrolyte breaks up into its ions and the ions carry the current to complete the circuit. 
 Basically electrolytes will conduct, non-electrolyte won't. 
A strong electrolyte produces a large number of ions giving high conductivity values. 
Example: H3PO4-->3 H+ + PO4-3 
A non- electrolyte does not break up into ions. 
Example: CH3OH(l) --> CH3OH(aq) 
*Procedures 
See lab 
*Tips 
You don't need a lot of the solution, just enough to cover the probe 
*Questions 
# Separate the above solutions into ionic compounds, molecular compounds, and acids. 
# Why would you expect ionic cpds to conduct and molecular cpds to not conduct? (use chemical reactions) 
# Why do HCl and H3PO4 conduct more than HC2H3O2?
# Explain the difference in the conductivity values between the distilled and tap waters.
