Bronsted-Lowry Definition of Acids and Bases (1923)

This theory looks at the role of the WHAT or WHAT

This theory looks at the role of the ACID or BASE

Proton = WHAT

H+ (Hydrogen ion)

An acid is a WHAT

Chemical species (anion, cation or molecule) that LOSES a proton

An base is a WHAT

Chemical species (anion, cation or molecule) that GAINS a proton

Water does WHAT have to be involved

Water does NOT have to be involved

A Bronsted-Lowry acid doesn’t necessarily have to produce an WHAT solution…it depends on what accepts the proton

A Bronsted-Lowry acid doesn’t necessarily have to produce an ACID solution…it depends on what accepts the proton

An acid/base reaction is a chemical reaction in which WHAT is transferred from an WHAT to a WHAT forming a WHAT and a WHAT

An acid/base reaction is a chemical reaction in which PROTON (H+) is transferred from an ACID to a BASE forming a NEW ACID and a NEW BASE

This theory explains how some chemical species can be used to WHAT both acids and bases

neutralize

A substance that appears to act as a Bronsted-lowry acid in some reactions and a Bronsted-Lowry base in other reactions is said to be WHAT
