Question

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 hydroxide Na(OH)2 Na(OH)3 Na2OH NaOH

Answer 1

The answer above is wrong. Imagine verifying an answer that isn't even among the options above.

Ahem, the actual answer is: Na2SO4

Step-by-step explanation:

Answer 2

NaOH is the Answer.

Step-by-step explanation:

By criss crossing the charge numbers, we find the chemical formula of a compound

For example Aluminium chloride

Al has 3+ charge and Cl has 1- charge

3 becomes the subscript of Cl and 1 becomes the subscript of Al

So the chemical formula will be
`Al_1 Cl_3`

Sodium Hydroxide is NaOH as Na the charge is
`1^+` and as OH, the charge is
`1^-`

Sodium phosphate is
`Na_3 PO_4` as sodium has
`1^+` charge and phosphate has
`PO_4^3-` charge.

Sodium sulfate is
`Na_2 SO_4` as sodium has
`1^+` charge and sulfate has
`SO_4^2-` charge.

Sodium chloride will be NaCl as sodium has
`1^+` charge and chloride has
`1^-` charge.

Calcium phosphate will be
`Ca_3 (PO_4 )_2` because Calcium possess
`2^+` charge and phosphate has
`PO_4^3-` charge.
