CHE 1302 Lecture Notes - Lecture 10: Litmus, Conjugate Acid, Ammonia
Document Summary
Baker | che 1302 | summer 2017 | lecture 10 | page 1. Typical acids: hcl (strong), ch3cooh (weak), hc2h3o2 (common in textbook) Acids and bases are defined by their properties. Neutralize a base and hence lose their acidic properties. Neutralize an acid and lose their basic properties. Acids form h+ in water: 2 +(cid:4666)(cid:1869)(cid:4667)+ (cid:4666)(cid:1869)(cid:4667) Bases form oh- in water: (cid:1840)(cid:1841)2 (cid:1840)+(cid:4666)(cid:1869)(cid:4667)+(cid:1841) (cid:4666)(cid:1869)(cid:4667) Neutralization reactions are essentially: +(cid:4666)(cid:1869)(cid:4667)+(cid:1841) (cid:4666)(cid:1869)(cid:4667) (cid:2870)(cid:1841)(cid:4666)(cid:4667: however, this description is not suitable in all cases, many bases (nh3, carbonates, etc. ) don"t contain oh- Defines acids and bases in terms of proton (h+) transfer. An acid-base reaction is a proton transfer process. Baker | che 1302 | summer 2017 | lecture 10 | page 2. An acid and a base that differ from each other by h+ are known as a conjugate pair. Conjugate base - the acid minus the donated proton. A- is the conjugate base of the acid ha.
