🔍 Key Concepts

• Material Safety Data Sheets (MSDS) / Safety Data Sheets (SDS) for sulfuric acid • Typical appearance and odor of strong inorganic acids • Difference between mineral acids (like sulfuric) and organic solvents (often fruity odor)

💭 Think About

• Think about what you know about strong laboratory or battery acids: do they usually have a pleasant smell, or little to no odor? • Consider which option best matches a very corrosive, dense, oily (syrupy) liquid used in batteries and industrial processes. • Eliminate any options that sound more like organic chemicals (esters, solvents) rather than a strong mineral acid.

✅ Before You Answer

• Verify which description mentions a syrupy / oily consistency, which is typical of concentrated sulfuric acid. • Check which answers claim a pleasant or fruity odor—ask yourself if that is realistic for a highly corrosive acid. • Confirm that sulfuric acid is typically clear or slightly hazy and has little to no characteristic odor rather than a strong pleasant smell.
