Question

Dumbledore thinks the students are now confident with significant figures; Snape is not so confident of this... Begrudgingly Snape decides to move forward in his lesson. His next lesson is in naming ionic compounds. He presents his students with sodium hydrogen sulfate and potassium permanganate. Which pair of ionic formulas is correct for these two compounds?

(A) NaHSO3, KMnO4
(B) NaHSO2, KMnO4
(C) NaHSO4, KMnO4
(D) NaHSO4, KMnO3
(E) NaHSO3, KMnO3

Answer 1

C)
`NaHSO_(4), KMnO_(4)`

Step-by-step explanation:

- For the sodium hydrogen sulfate:

The ending -ate of the word sulfate indicates that the compound comes from the ion sulfate that is
`SO_(4)^(-)`, so the compound formed by this ion will be
`NaHSO_(4)`

- For the potassium permanganate:

The ending -ate of the word permanganate indicates that the compound comes from the ion
`MnO^(-)_(4)`, so the compound formed by this ion will be
`KMnO_(4)`
