Chapter 9 Flashcards
Base
A substance that when put in water increases the concentration of OH- ions or a substance that accepts H+ ions
Contains lone pairs
Strong bases
Bases that completely ionize in water
Congugate acid base pairs
Each acid has a conjugate base and every base is a conjugate acid
What happens when acids and bases mix
With strong acids and bases in aqueous solutions react with each other they form water and a salt
Polyprotic acids
Acids that release more than one H+
KE=
(1/2)mv^2
Acids
Contain H
Do strong acids form strong conjugate bases?
No
When dealing with acids and bases, K=
Concentration of products/concentration of reactants
When Ka is large,
The acid is strong
Does equilibrium favor the formation of weak or strong acids
Weak
Kw (ion-product constant)=
[H3O+][OH-]
Kw=1.0x10^-14
In .1M HCl how much H3O forms when HCl is put in water?
.1M
pH=
-log[H3O+]
A salt derived from a strong base and weak acid forms what kind of solution?
Basic
Kb vs Ka
Base ionization constant and acid ionization constant
Strong electrolytes
Solutes that completely dissociates into ions when dissolved in water
Non-electrolytes
Solutes that dissolve in water without separating and ions
[OH]=Kw/[H3O]
What is Kw
1.0x10^-14
Since a strong acid like hydrochloric acid is completely dissociated in aqueous solution the solution of the acid tells us what
The number of hydronium ions present
.1M of HCl completely dissociates so the concentration of H3O+ is .1M
What forms when you mix a strong acid in a strong base
Water and salt
Result of a reaction of an acid with a bicarbonate or carbonate
The acid and base react to form a salt and carbonic acid which decomposes to CO2 and water
