View photos of the elements Oxidation Number Rules The sum of all the Oxidation Number, ON, over all the atoms in a chemical species is equal to the charge on the chemical species In their compounds, the alkali metals and the alkaline earths have ON of +1 and +2 respectively. In compounds the ON of fluorine is almost always . . . → Read More: Oxidation Number Rules Names of Polyatomic ions and their Charges In this course, you will need to learn some polyatomic ions. Be sure to learn their names, formulas and their charges. Cation: ammonium, NH4+ Anions: nitrate, NO3– acetate, C2H3O2– sulfate, SO42- hydroxide, OH– phosphate, PO43- carbonate, CO32- cyanide, CN– chlorate, ClO3– permanganate, MnO4– chromate, CrO42- dichromate, Cr2O72- . . . → Read More: Ions to learn The following table summarizes the solubility ionic compounds in water formed with these common anions . Use this as a guide to predict products of chemical reactions for double-replacement reactions. Anions Soluble Insoluble Nitrates, NO3– ALL – Acetates, C2H3O2– ALL – Chlorides, Cl– ALL, except … AgCl, Hg2Cl2, PbCl2 Sulfates, SO42- ALL*, except . . . → Read More: Solubility Rules!! |
