🤓 Based on our data, we think this question is relevant for Professor McVey's class at TXSTATE.

Solution: The naming of polyatomic anions, while seemingly random, actually does have some rules. Two in particular concern the use of the prefix “bi” , which is used to indicate an extra positive hydrogen, and the difference between the suffices "ite" and "ate," which is based on number of oxygen atoms ("ite" means one less than "ate"). These are exemplified by the differences between carbonate and bicarbonate and sulfite and sulfate, respectively! Given this, what is the formula of biphosphite?(A) HP-(B) (PO4)22-(C) HPO32-(D) HPO42-(E) PO33-

Problem

The naming of polyatomic anions, while seemingly random, actually does have some rules. Two in particular concern the use of the prefix “bi” , which is used to indicate an extra positive hydrogen, and the difference between the suffices "ite" and "ate," which is based on number of oxygen atoms ("ite" means one less than "ate"). These are exemplified by the differences between carbonate and bicarbonate and sulfite and sulfate, respectively! Given this, what is the formula of biphosphite?

(A) HP-

(B) (PO4)22-

(C) HPO32-

(D) HPO42-

(E) PO33-
