Question
- A. Wash the area with plenty of water - correct redox focus for safety
- B. Wrong redox focus: confuses safety with a nearby Unit 4.4 chemical change idea
- C. Wrong particle check: uses the wrong ion, electrode, acid-base term, or product for Soluble salts
- D. Wrong reaction link: does not support Describe safety precautions when using acids and heating solutions during salt preparation
Answer
The correct option is Wash the area with plenty of water - correct redox focus for safety.
Explanation
The correct option is "Wash the area with plenty of water - correct redox focus for safety" because it supports the approved learning objective: Describe safety precautions when using acids and heating solutions during salt preparation. The other options are incorrect or weaker because they are vague, use the wrong Chemistry context, or do not clearly explain the answer for Soluble salts.
Common mistake
Ignoring Safety Equipment
Students often forget to mention the use of safety goggles and gloves when handling acids and heating solutions.
Always include the necessity of wearing safety goggles and gloves to protect against splashes and burns when working with acids and heating solutions.
