(Keep as notes) Naming Chemical Cmpds Pd.
1. Ionic Compounds. -- this has already been discussed in great detail. Basically, you simply name the two ions involved. If the cation involved has more than one possible charge, you must indicate the oxidation # in the name by using the roman numeral Stock naming system, or the classical system with the latin name and ending.
Writing formulas: you simply put the formula of the ionic compound followed by a "" and xH2O. "x" being the number of water molecules that bond per formula unit.
Naming hydrates: write the name of the ionic compound as normal, then add the correct numerical prefix in front of the word "hydrate" to indicate the number of water molecules bonded per formula unit.
|anhydrous compound||formula of hydrate||hydrate name|
|CuSO4||CuSO4 5H2O||copper(II) sulfate pentahydrate|
|BaCl2||BaCl2 2H2O||barium chloride dihydrate|
|calcium chloride dihydrate|
|sodium sulfide nonahydrate|
|Ni(NO 3) 2 6H2O|
3. Binary Molecular compounds -- these are compounds consisting of two elements covalently bonded together. (ex SO2, CO, NH3) The name consists of two words that reflect the elemts involved and the number of atoms.
First Word: numerical prefix + name of element * NOTE: for the first word, if only one atom is present DO NOT Use Prefix (see CO2 below)
Second Word: numerical prefix + name of element with "ide" ending.
