Chapter 4 Aqueous Solutions Flashcards
Non electrolyte
Aqueous solution without ions
Solutions can be ____________ or _____________ depending on how many _______ are present
Electrolytes(strong or weak)
Nonelectrolytes
Ions
Acids ionize in an aqueous solution to produce
H+ ions (proton donors)
Bases ionize in an aqueous solution to produce
Oh - (proton acceptors)
Strong acids and bases ionize
100%
______________ only ionize partially
Weak acids and bases
Ionic strong electrolytes
All soluble (strong bases included)
Stron electrolytes molecular
Strong acids
Weak electrolytes ionic
Slightly soluble
Weak electrolyte molecular
Weak acids and bases
Non electrolytes ionic
Insoluble
Non electrolytes molecular
All other compounds
Strong acids are
Molecular
Strong bases are
Ionic
Weak electrolytes do not separate in net ionic equations
True
Redox reaction
A reaction in which electrons are transferred from one atom to another
Redox reaction parts
Oxidation and reduction
OILRIG
Oxidation is loss
Reduction is gain
To determine changes in oxidation numbers use:
H is +1
O is -2
F is -1
Elements in their natural state are zero
Oxidation can be viewed as an ___________ in charge
Increase
Reduction can be viewed as an __________ in charge
Decrease
Redox reactions which are single replacement reactions can be predicted using the
Activity series of metals (higher up it is easier it will react)
Activity series has no use in
Double replacement reactions
Molarity
Miles of solute / volume of solution in liters
Expressing the concentration of an electrolyte
The concentration of ions Depends on chemical formula
In dilution miles of solute will stay same but volume of water will increase
True
Titration
The process of adding a solution with a known concentration to a solution of unknown concentration
Ewuivalence point
When concentration of h+ ions equals concentration of oh - ions in a acid base titration
Endpoint
When a change in color happens in a titration
Electrolyte
A solution containing ions
