Hint: 11 ed.: p.p. 127‐128; 10 ed. p. 130; 9 ed. p. 128. Example 4.3. You need to memorize the definition. Definition: Brǿnsted acids must contain available (releasable) hydrogen ions while the Brǿnsted bases must be able to accept hydrogen ions. To obtain Bronsted acid, simply add H+; to obtain Bronsted base, simply subtract H+. 4. Which of the following underlined atoms contains the oxidation number as ‐1?
