Flashcards in Acids And Bases Deck (18)
When does ionization occur and what does it produce from an acid?
Occurs when an ionic compound dissociates in water.
Produces a proton (H+) or a hydronic ion (H3O+)
What is Ka, if Ka is high Whats favoured?
Acid ionization constant -reflects fraction of an acid that is ionized.
Products are favoured or the acid is strong. (Dissociates almost completely)
Describe Arrhenius Acids and Bases
Acids- substance that yields a proton (H+)
Bases- substances that yield a hydroxide ion (OH-)
Describe Brønsted- Lowry acids and bases
Acid- Proton donor
Base- Proton acceptor
Can now include bases that don’t have hydroxide ion (NH3)
Describe Lewis Acids and Bases
Acids- accept a pair of electrons
Bases- donate a pair of electrons
Ion product constant for water and aqueous solutions
What does ionizing partially result in
Why do some acids have more than 1 Ka?
They have more than 1 ionizable hydrogen
Ka decreases with each ionizable proton because they don’t want to get more negative by losing more protons
Why is water not in Ka Formula
Water is a liquid and doesn’t change in concentration
Base dissociation constant
What does concentrated and dilute indicate
How much of an acid or base is dissolved in solution
A water molecule that looses a hydrogen ion and becomes a negatively charged hydroxide ion (OH-)
Water molecule that gains a hydrogen ion and becomes a positively charged hydronium ion (H3O+)
Negative logarithm of the hydrogen ion concentration
Negative logarithm of the hydroxide ion concentration
Acts as both an acid and a base (water)
Having 1 ionizable hydrogen
Particle formed when a base gains a hydrogen ion
Particle that remains when an acid has donated a hydrogen ion
