Verified step by step guidance1
Step 1: Recognize that HCl is a binary acid composed of hydrogen and a halogen (chlorine). Binary acids are named based on the halogen element attached to hydrogen.
Step 2: Understand the naming convention for binary acids: the prefix 'hydro-' is added to the root of the halogen name, followed by the suffix '-ic', and then the word 'acid'.
Step 3: Apply this rule to chlorine: the root is 'chlor', so adding the prefix and suffix gives 'hydrochloric acid'.
Step 4: Note that names like 'chlorous acid' and 'chloric acid' refer to oxyacids of chlorine, which contain oxygen atoms, unlike HCl which does not contain oxygen.
Step 5: Conclude that the correct name for HCl as a strong acid is 'hydrochloric acid'.
