Thus, AsCl 3 . is arsenic trichloride. Now obviously this does not include the rules for naming the many categories and thousands of organic compound. This will be discussed at another time. CCl 4 is carbon tetrachloride. Naming acids is based on whether they are binary or ternary.
Ternary acids contain oxygen as a part of a polyatomic anion.
It gets a little trickier when there are even more possibilities for the amounts of oxygen. Now, it's time to try your luck. HNO 2 7. KIO 2 10. SiO 2 13.
