Based upon the ion charge of the following polyatomic ions, predict the formula for the following compounds. sulfate = SO4 -2 phosphate = PO4 -3 hydroxide = OH- sodium sulfate

NaSo4

Na2SO4

Na(SO4)2

NaSO8

Since the sodium ion is Na+, and sulfate is SO4(2-), you'll need 2 sodiums for a sulfate, making sodium sulfate Na2SO4.

Answer:

The correct answer is \(Na_2SO_4\).

Explanation:

Given polyatomic ions:

1) Sulfate =\(SO_{4}^{2-}\)

2) Phosphate = \(PO_{4}^{-3}\)

3) Hydroxide =\(OH^-\)

The formula of Sodium sulfate will be:

\(2Na^++ SO_{4}^{2-}\rightarrow Na_2SO_4\)

Sodium carries 1+ charge and and sulfate ion carries 2-charge. In order to neutralize negative charge on sulfate ion two sodium ions will be needed.
