The compound, NaH₂PO₄, is present in many baking powders. What is its name? A) sodium biphosphate B) sodium hydrogen phosphate C) sodium dihydrogen phosphate D) sodium hydrophosphate E) sodium dihydride phosphate

Question

Quizplus · Accepted Answer

The compound consists of one sodium ion (Na+) and two phosphate ions. The first phosphate ion (H2PO4-) is known as dihydrogen phosphate, and when one of its hydrogen atoms is removed, it becomes hydrogen phosphate (HPO42-). The second phosphate ion (PO43-) is known as orthophosphate. Therefore, the compound can be named sodium dihydrogen phosphate, or sodium monohydrogen phosphate, or sodium phosphate monobasic. Out of the given options, only option C, sodium dihydrogen phosphate, matches the description.
