Web• Every acid-base reaction contains two conjugate acid-base pairs because an H+ is transferred in both the forward and reverse directions. When an acid such as HF loses one H+, the conjugate base F-is formed. When H 2 O acts as a base, it gains one H+, which forms its conjugate acid, H 3 O+. Practice Problems 8. WebSep 27, 2024 · The Au 3+ ion, because of its higher positive charge, is a harder acid than Au + and can form complexes with harder bases such as H 2 O and amines. In keeping with the "like binds like" principle, the compound AuI (soft-soft) is stable, but AuI 3 (hard-soft) is unknown. Conversely, AuF has never been isolated but AuF 3 (hard-hard) is stable.

WebThis quiz is designed to follow my Acids and Bases tutorial video series. But I'm not looking to see if you simply ‘memorized' the concepts. The videos use simple examples to demonstrate concepts, these questions will test you at a slightly higher level.
