Acids And Bases Flashcards
What is the Arrhenius definition of an acid?
An acid is a substance that dissociates in water to produce H+ ions
What is the Arrhenius definition of a strong acid?
A strong acid is a substance that almost completely dissociate in water to give hydrogen ions
What is the Arrhenius definition of a weak acid?
A weak acid is a substance that only slightly dissociates in water to give hydrogen ions
What is the Arrhenius definition of a base?
A base is a substance that dissociates in water to produce OH- ions
What is the Arrhenius definition of a strong base?
A strong base is a substance that almost completely dissociates in water to give hydroxide (hydroxyl) ions (OH-)
What is the Arrhenius definition of a weak base?
A weak base is a substance that only slightly dissociates in water to give hydroxide ions (OH-)
What is the Bronsted-Lowry definition of an acid?
An acid is a proton donor
What Bronsted-Lowry definition of a base?
A base is a proton acceptor
What is a the Bronsted-Lowry definition of a strong acid?
A good proton donor
What is the Bronsted-Lowry definition of a weak acid?
A poor proton donor
What is the Bronsted-Lowry definition of a strong base?
A good proton acceptor
What is the Bronsted-Lowry definition of a weak base?
A poor proton acceptor
What does an acid change into it’s conjugate base?
An acid changes into it’s conjugate base when it donates a proton
When does a base change into it’s conjugate acid?
When it accepts a proton
What is a conjugate acid-base-pair (conjugate pair)?
Any pair consisting of an acid and a base that differ by one proton
