Question

Which of the following polyatomic ion pairs have the same charge?

a. Sulfate and Phosphate
b.Carbonate and hydroxide
c.Ammonium and Nitrate
d. More than one correct response
e. No correct response

Answer 1

The pairs of polyatomic ions that have the same charge are Sulfate and Phosphate, Carbonate and Hydroxide, and Ammonium and Nitrate.

Step-by-step explanation:

The pairs of polyatomic ions that have the same charge are:

1. Sulfate and Phosphate: Both are anions with a charge of 2-
2. Carbonate and Hydroxide: Both are anions with a charge of 1-
3. Ammonium and Nitrate: Ammonium is a cation with a charge of 1+, and Nitrate is an anion with a charge of 1-

Therefore, the correct response is d. More than one correct response.
