Chemistry Lecture Notes September 8, 2006 Work end of chapter problems: Ch 3: 2, 5, 6 Naming Bases Base – a substance that yields hydroxide ions (OH-) when dissolved in water. Many bases have a cation with OH- ions o Examples LiOH, Ba(OH)2 Name the bases as the ionic compound it is. One common base which doesn’t have OH- is NH3 called ammonia. Naming Hydrates Hydrate – compounds that have a specific number of water molecules attached to them. Example CuSO4*5H20 See the dot between compound and water, being shown a hydrate. To name, use the prefix to tell how many waters and use the word hydrate instead of water. The above would be called copper (II) sulfate pentahydrate. Practice: o Name the following: Fe2(SO4)3 – ionic – cation first, Iron, then anion, Sulfate. Iron (III) Sulfate AlPO3 – ionic – aluminum phosphate (take one away, -ite ending) H2SO3 – acid (hydrogens at beginnings followed by anion) Sulfite
