Quizplus · Accepted Answer

The pyrophosphate ion has the formula P2O7 4-. This is represented in choice D as P₂O₇⁴⁻, where the two P atoms are connected by an oxygen bridge (designated by the O in the middle) and each P atom is bonded to four oxygen atoms (represented by the S symbols) except for the two terminal oxygens (represented by the O outside the P atoms), which carry a negative charge (represented by the - at the end of the formula).
