Conjugate Acids and Bases Section 3 Acid-Base Reactions Chapter 14 Conjugate Acids and Bases Conjugate base - species that remains after a Brønsted-Lowry acid has given up a proton acid conjugate base

Neutralization Reactions Section 3 Acid-Base Reactions Chapter 14 Neutralization Reactions

Strength of Conjugate Acids and Bases Section 3 Acid-Base Reactions Chapter 14 Strength of Conjugate Acids and Bases The stronger an acid is, the weaker its conjugate base The stronger a base is, the weaker its conjugate acid strong acid base acid weak base

Strength of Conjugate Acids and Bases Section 3 Acid-Base Reactions Chapter 14 Strength of Conjugate Acids and Bases Proton transfer reactions favor the production of the weaker acid and the weaker base. stronger acid stronger base weaker acid weaker base The reaction to the right is more favorable weaker acid weaker base stronger acid stronger base The reaction to the left is more favorable
