Question

The following list contains some common polyatomic ions. Using the charge on these ions and the idea of valence,

predict the formulas for the compound formed from the following:
potassium and permanganate

A) K(MnO4)
B) K4MnO4
C) K4MnO
D) KMnO4

Answer 1

Answer: or Sodium carbonate.

or Potassium permanganate

Explanation: ion carries 1 + charge whereas carbonate ion carries overall charge of -2. So for every carbonate ion, two sodium ions combine to balance the charges and thus form a stable compound,

Potassium ion carries 1 + charge where as permanganate ion carries overall charge of -1. So for every permanganate ion, one potassium ion combines to balance the charges and thus form a stable compound, Explanation:
