(i) What is substance B ?
(ii) What is the purpose of B ?
(iii) Why is iron[III] chloride to be stored in a closed container ?
(iv) Write the equation for the reaction between iron and chlorine.
Answer
(i) Substance B is fused calcium chloride.
(ii) Iron (III) chloride is highly deliquescent so it is kept dry with the help of B [fused calcium chloride (drying agent)]
(iii) Iron[III] chloride is to be stored in a closed container because iron (III) chloride is highly deliquescent and it absorbs moisture from the surrounding air to form a saturated solution.
(iv) 2Fe (heated) + 3Cl2 (dry) ⟶ 2FeCl3

Robert bought a bottle of cleaning agent to clean his kitchen sink. He noticed a warning label on the bottle — "Use with Caution". Curious about its nature, he tested the solution using litmus. The red litmus turned blue, while the blue one remained unchanged. Later he learned that bases like sodium hydroxide, ammonium hydroxide are commonly used for cleaning as they can dissolve grease and organic waste. Such substances can be hamful to the skin and eyes if not handled properly.
(a) Why is a basic solution used in drain cleaners ?
