A tin box has two brown bottles containing 25mL of each reagent-reagent 1 (ferric chloride 33mL/L and strong hydrochloric acid967mL/L) and reagent 2 (chloroform 1000mL/L). A spontaneous explosion occurred and a coloured liquid was spilled out. What chemical reaction may have occurred and what gas might have formed?How could the formation of this gas lead to an explosion? What possible side effects a person suffers when exposed to such accident? (Do they last long? Why?)
