Acid Nomenclature (the words) formula to name Step 1: name the anion Step 2: change the name of the anion HUH?!?!?!?

Acid Nomenclature (the words) The Rules anion acid name stemide hydrostemic acid stemite stemous acid stemate stemic acid I ate something icky at the White House

Acid Nomenclature (the words) formula to name Step 1: name the anion Step 2: change the name of the anion Step 3: The End

Acid Nomenclature (the words) name to formula Step 1: write the symbol for the anion Step 2: balance the charge by adding hydrogen(s) in front Step 3: add an (aq) at the end Step 4: The End charge on the anion = # of hydrogens in acid

bromous acid nitric acid periodic acid hydrosulfuric acid permanganic acid hydrofluoric acid phosphorous acid sulfuric acid hypochlorous acid

bromous acid 1) change acid name to anion name bromous acid  bromite 2) write symbol for anion bromite = BrO2-1 3) add hydrogen and (aq) charge = -1, so need 1 H BrO2-1  HBrO2(aq) done

nitric acid 1) change acid name to anion name nitric acid  nitrate 2) write symbol for anion nitrate = NO3-1 3) add hydrogen and (aq) charge = -1, so need 1 H NO3-1  HNO3(aq) done

periodic acid 1) change acid name to anion name periodic acid  periodate 2) write symbol for anion periodate = IO4-1 3) add hydrogen and (aq) charge = -1, so need 1 H IO4-1  HIO4(aq) done

hydrosulfuric acid 1) change acid name to anion name  sulfide 2) write symbol for anion sulfide = S-2 3) add hydrogen and (aq) charge = -2, so need 2 H S-2  H2S(aq) done

permanganic acid 1) change acid name to anion name permanganic acid  permanganate 2) write symbol for anion permanganate = MnO4-1 3) add hydrogen and (aq) charge = -1, so need 1 H MnO4-1  HMnO4(aq) done

hydrofluoric acid 1) change acid name to anion name hydrofluoric acid  fluoride 2) write symbol for anion fluoride = F- 3) add hydrogen and (aq) charge = -1, so need 1 H F-  HF(aq) done

phosphorous acid 1) change acid name to anion name phosphorous acid  phosphite 2) write symbol for anion phosphite = PO3-3 3) add hydrogen and (aq) charge = -3, so need 3 H PO3-3  H3PO3(aq) done

sulfuric acid 1) change acid name to anion name sulfuric acid  sulfate 2) write symbol for anion sulfate = SO4-2 3) add hydrogen and (aq) charge = -2, so need 2 H SO4-2  H2SO4(aq) done

hypochlorous acid 1) change acid name to anion name hypochlorous acid  hypochlorite 2) write symbol for anion hypochlorite = ClO-1 3) add hydrogen and (aq) charge = -1, so need 1 H ClO-1  HClO(aq) done
