(17 cards)
He came up with the pH scale to measure hydrogen ion concentrations in solutions while working at the Carlsberg research lab in Copenhagen.
Søren Sørensen
The pH scales typically runs form __ to __
0, 14
The scale at which a solution is considered acidic.
1 - 6
The scale at which a solution is considered neutral.
7
The scale at which a solution is considered alkaline.
8 - 14
In 1884, he proposed the definitions for acids and bases.
Svante Arrhenius
ARRHENIUS ACIDS AND BASES
A substance that produces H3O+ ions in aqueous solution.
Acid
ARRHENIUS ACIDS AND BASES
A substance that produces OH- ions in aqueous solution.
Base
BRØNSTED ACIDS AND BASES
A proton donor
Acid
He proposed definitions for acids and bases as proton donors and proton acceptors, respectively
Brønsted
BRØNSTED ACIDS AND BASES
A proton acceptor
Base
BRØNSTED ACIDS AND BASES
This is what remains of the acid after the donation of a proton.
Conjugate Base
BRØNSTED ACIDS AND BASES
Newly formed protonated species. (base)
Conjugate Acid
It is a reaction that involves the donation of a pair of electrons from one species to another.
A Lewis acid-base Reaction
LEWIS ACIDS AND BASES
It is a substance that can donate a pair of electrons.
Lewis Base
LEWIS ACIDS AND BASES
It is a substance that can accept a pair of electrons
Lewis Acid
