Cards

Term
Define Chemical Equlibrium (closed book)
Definition
The point at which both the forward and reverse reactions in a chemical equation have equal reaction rates.
Term
Define La Chatelier's Principle (closed book)
Definition
When a stress (such as change in concentration, pressure, or temperature) is applied to an equlibrium, the reaction will shift in a way that relieves the stress and restores equilibrium.
Term
Define Acid Ionization reaction (closed book)
Definition
The reaction in which an H+ separates from an acid molecule that it can be donated in another reaction
Term
What does "ph" stand for? (closed book)
Definition
Potential Hydrogen
Term
Define oxidation number (closed book)
Definition
The charge that an atom in a molecule would develop if the most electronegative atoms in the molecule took the shared electrons from the less electronegative atoms.
Term
Study the rules of determining oxidation number on page 528. You will not need to memorize the rules but you will need to know how to use the rules in a problem
Definition
Study Example 16.2 on page 529
Term
Define oxidation (closed book)
Definition
The process by which an atom loses electrons
Term
Define Reduction (closed book)
Definition
The process by which an atom gains electrons
Term
Study example 16.3 for oxidation and reduction problems on page 532 (open book)
Definition
Term
Study example 16.4 for recognizing reduction/oxidation reactions on page 533 and 534 (open book)
Definition
Term
Be able to recognize when chemical equlibrium occurs on a chart such as the one on page 492 (open book)
Definition
Term
What does the ph scale measure? (closed book)
Definition
The acidity or basicity of a solution.
Term

Study example 15.1 on page 496

 

Understand how to solve for "K" (equilibruim constant)

 

Know equation 15.2

 

(open book)

Definition
Term

Remember a solid and/or liquid is not included in equation 15.2

 

Remember aqueous solutions are included in equation 15.2

 

Study example 15.2 on page 501

 

open book

 

Definition
Term

(closed book)

Be able to recognize if a substance is acidic or base by looking at their ph

 

Know the range of a:

 

stong acid

weak acid

neutral

weak base

strong base

Definition

stong acid: ph of 0 - 1.9 ph

weak acid: ph of 2 - 6.9

neutral: ph of 7

weak base: ph of 7.1 - 12

strong base: ph 12.1 - 14

Term

(closed book)

Be able to order acids in terms of increasing ionization constants.

Definition

The higher the pH, the weaker the acid. The weaker the acid, the smaller the ionization constant. Thus, high pH means low ionization constant.

Term

(Open Book)

Understand how the chemical equilibirum can be shifted if the equilibrium has a stress applied to reaction

 

 

Definition
Study example 15.4
Term

(Open Book)

 

Be able to recognize if a chemical reaction is at chemical equilibrium

 

Definition
Study example 15.3
Term

(open book)

 

Know how to predict a chemical reaction that is at chemical equilibrium if pressure is added

 

 

Definition
Study example 15.5
Term

(Open book)

 

Know how to predict a chemical reaction that is at chemical equilibrium if temperature is added

Definition
Study example 15.6
