Which of the following is the correct chemical name for the ionic compound NaCl?
A
Sodium chlorate
B
Sodium chlorite
C
Sodium chloride
D
Sodium carbonate
Verified step by step guidance1
Identify the ions present in the compound NaCl. Sodium (Na) is a metal and forms a cation with a +1 charge, written as Na\^{+}. Chlorine (Cl) is a nonmetal and forms an anion with a -1 charge, written as Cl\^{-}.
Recognize that NaCl is an ionic compound formed by the combination of Na\^{+} and Cl\^{-} ions in a 1:1 ratio to balance the charges.
Recall the naming convention for ionic compounds: the cation (metal) name is written first, followed by the anion (nonmetal) name with its ending changed to '-ide'.
Apply the naming rule: the cation Na\^{+} is named 'Sodium', and the anion Cl\^{-} is named 'Chloride'.
Conclude that the correct chemical name for NaCl is 'Sodium chloride', distinguishing it from other names like 'Sodium chlorate' or 'Sodium chlorite', which refer to different polyatomic ions.
