Which of the following acid is also known as spirit of salts?

• A. Sulphuric acid
• B. Nitric acid
• C. Hydrochloric acid
• D. Oxalic acid

Hint:

Link the old name to the source: \textbf{Spirit of Salt} comes from reacting an acid with \textbf{salt} (\(NaCl\)) to produce \textbf{Hydrochloric Acid}.

Answer 1

The Correct Option is C

Step 1: Define the term. "Spirit of salt" is an old name for a chemical, stemming from its creation process.

Step 2: Determine the acid. Previously, hydrochloric acid (\(HCl\)) was made by combining common salt (sodium chloride, \(NaCl\)) with sulfuric acid. The volatile "spirit" created from salt was thus called spirit of salt.

Step 3: Summary. Spirit of salt is now known as hydrochloric acid.
