(a)
Interpretation:
The formula of the compound formed when K+ combines with OH- should be determined
Concept Introduction:
Polyatomic ions are cations or anions with more than one atom. The ion holds the charge because the total number of electrons and total number of protons in the nuclei of all atoms are different.
(b)
Interpretation:
The formula of the compound formed when K+ combines with NO2- should be determined.
Concept Introduction:
