Question

Which of the following polyatomic ions will form an ionic compound with a single sodium ion?

CO32−
HCO31−
SO42−
SO32−

Answer 1

Answer:

Option B, HCO3 1-

Explanation:

The valence of Sodium ion is +1 and the valence of HCO3 is -1. Thus, sodium ion has an extra electron to be donated to complete its outer shell while HCO3 needs an electron to complete its outer shell

Hence Na will combine with HCO3 to form NaHCO3
