Which of the following ionic compounds is paired incorrectly with its name?
A
MgS - Magnesium Sulfate
B
CaO - Calcium Oxide
C
KBr - Potassium Bromide
D
NaCl - Sodium Chloride
Verified step by step guidance1
Identify the chemical formula for each compound and the corresponding ions involved. For example, MgS consists of magnesium (Mg) and sulfur (S) ions.
Recall the naming conventions for ionic compounds: the name of the metal (cation) is followed by the name of the non-metal (anion) with its ending changed to '-ide'.
Apply the naming convention to each compound: MgS should be named Magnesium Sulfide, not Magnesium Sulfate.
Verify the names of the other compounds: CaO is correctly named Calcium Oxide, KBr is correctly named Potassium Bromide, and NaCl is correctly named Sodium Chloride.
Conclude that the incorrect pairing is MgS - Magnesium Sulfate, as the correct name should be Magnesium Sulfide.
