Nomenclature of Some Special Cations. I. Cations that do not require Roman numerals: Previously you had learned that elements in Groups IA and IIA, and aluminum form cations of a. fixed charge. You are now going to add on to this list, a few more ions in the transition metals that. also do not require a fixed charge because they generally form only ions with charges as shown. below:
Take an example, if a recipe calls for 350 grams of plain flour, then you refer to a conversion table saying it's about 2.5 cups.
It calls for: 2-1/2 cups + 1 T. or 2â cups + 1 T. pastry flour (or bleached all-p. flour), lightly spooned into the cup and leveled off (10.2 ounces or 290 grams). yikes!!! To make matters more complicated, her recipe in Epicurious calls for 2 cups + 3 T. pastry flour.
