Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line

Experiment 9- Reactions in Aqueous Solutions: Methathesis Reactions and Net Ionic Equations

front 1

Purpose of Experiment 9

back 1

become familiar w/ writing equations for metathesis reactions,

including net ionic reactions

front 2

Metathesis reaction model

back 2

when cations and ions appear to exchange partners

front 3

What must happen for a metathesis reaction to lead to a net change in solution?

back 3

ions must be removed from the solution

front 4

Three driving forces for metathesis to occur

back 4

1. Formation of a precipitate

2. The formation of a weak electrolyte or nonelectrolyte

3. The formation of a gas that escapes a solution

front 5

Typical reaction with formation of a precipitate

back 5

The reaction of barium chloride w/ sivler nitrate

produces AgCl precipitate

front 6

Molecular equation

back 6

a balanced chemical equation where the ionic compounds are expressed as molecules instead of component ions

front 7

Complete ionic equation

back 7

A form of writing a balanced equation in which all ions are shown

front 8

Net ionic equation

back 8

equations that show only the soluble, strong electrolytes reacting (represented as ions) and omit the spectator ions

front 9

spectator ions

back 9

ions that appear on both sides of a complete ionic reaction and are removed from the complete ionic equation to produce the net ionic equation

these ions exists in the same form on both the reactant and product sides of a reaction. They are unchanged on both sides of a chemical equation and do not affect equilibrium.
