CN- (aq) + H3O+ (aq) \rightarrow H2O (l) + HCN (aq) Identify the reactant that is a Bronsted-...


{eq}CN^-_{(aq)} + H3O^+_{(aq)} \rightarrow H_2O_{(l)} + HCN_{(aq)} \\ {/eq}Identify the reactant that is a Bronsted- Lowry Acid and the reactant that is a Bronsted- Lowry Base in the reaction.

Bronsted-Lowry Acids and Bases:

A Bronsted-Lowry acid is a proton donor. A Bronsted-Lowry base is a proton acceptor. In an acid-base reaction, a Bronsted-Lowry acid donates a proton to the Bronsted-Lowry base while the Bronsted-Lowry base accepts a proton from the Bronsted-Lowry acid.

The Bronsted-Lowry and Lewis Definition of Acids and Bases


Chapter 10 / Lesson 4

Chemist Johannes Bronsted and scientist Thomas Lowry proposed that an acid should be defined as a substance that can donate a proton, while a base is any substance that can accept protons. American chemist G.N. Lewis proposed a different theory. Learn about three popular scientific definitions of acids and bases.
