🔍 Key Concepts

• Lead-acid battery chemistry and what chemicals are commonly used • Difference between acids and salts (like chlorides) • Safety knowledge: which battery fluids are highly corrosive and require special handling

💭 Think About

• Which of these substances do you most commonly associate with car or ship service batteries? • Two of the options are types of chloride salts. Do lead-acid batteries normally use salts or a specific liquid acid in water? • Think about what fluid can burn skin and clothing and is often warned about on battery labels.

✅ Before You Answer

• Identify which options are acids used in batteries versus salts used for other purposes (like de-icing or cleaning). • Recall that a lead-acid battery name actually tells you the type of acid used. • Eliminate any option that is typically solid or used mainly for road salt or swimming pools rather than batteries.
