🔍 Key Concepts

• Chemical reaction between sulfuric acid and water when mixing electrolyte • Standard safety rule for diluting acids in a lab or engineering setting • Risks of splattering and excessive heat during mixing

💭 Think About

• Think about which liquid (acid or water) generates more heat when added to the other and how to control that heat safely. • Which procedure minimizes the chance of acid splashing back toward your face and hands? • In basic chemistry, what is the universal rule whenever you must combine concentrated acid and water?

✅ Before You Answer

• Recall the standard lab safety phrase about mixing acid and water; verify the correct order of pouring. • Consider which option would be most likely to cause violent reaction or splattering if done incorrectly. • Eliminate any answers that mention container types or stirring that are not part of the well-known acid–water safety rule.
