Term
Metathesis Reaction
Definition
Double replacement reaction where two compounds are mixed and exchange components.
Term
What is another way of saying Metathesis reaction?
Definition
Double replacement
Term
What are the observable results of chemical reactions?
Definition
Evolution of gas or heat, production of a precipitate, production of a weak electrolyte.
Term
What produces the results of a chemical reaction?
Definition
The rearrangement of ions.
Term
What is a precipitate?
Definition
A solid formed from a chemical reaction.
Term
Driving Force
Definition
The formation of products from a chemical reaction?
Term
How can you predict whether a reaction would produce a precipitate?
Definition
Precipitates form when at least one of the reaction products is insoluable in water.
Term
Net ionic equation
Definition
Where all the spectator ions are eliminated, leaving only ions that form the driving force product. Keep the coefficients for each ion/product.
Term
Spectator ions
Definition
Ions not involved in forming the driving force product.
Term
Which way is this laboratory designed to study chemical reactions?
Definition
Qualitatively
Term
Why is it not critical to measure out the reactants exactly?
Definition
It is a qualitative, not a quantitative study of the compound's changes.
Term
WHat measurement will you take of each solution?
Definition
Approximately 1 mL
Term
How should you dispose of the contents of the test tube?
Definition
By pouring them into the 150-mL beaker labled "Rinse Water and Reaction Mixtures"
Term
How should I prepare for my equipment for the next experiment?
Definition
Clean the test tubes and stirring rod with distilled water with the squirt wash bottle and pour the waste water into the waste beaker.
Term
What are the three types of equations?
Definition
Molecular, Complete Ionic and Net Ionic
