Tasks include comparing the reactivity of aluminium, copper, zinc and an unknown metal M using nitrate solutions and describing observed changes. Students then rank the metals by decreasing reactivity using both result tables. Further questions address redox reactions through Mg and silver nitrate, identifying oxidising agent behaviour, and require using properties of barium salts to complete formulas and explain poisoning risks from barium carbonate in hydrochloric acid.","Reactivity Series  \nQuestion paper  \n\n| Level | IGCSE(9-1) |\n| --- | --- |\n| Subject | Chemistry |\n| Exam Board | Edexcel IGCSE |\n| Module | Double Award (Paper 1C) |\n| Topic | Inorganic Chemistry |\n| Sub-Topic | Reactivity Series |\n| Booklet | Question paper |\n\nTime Allowed: 23 minutes  \nScore: /19  \nPercentage: /100  \nGrade Boundaries:  \n\n| 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- |\n| >90% | 80% | 70% | 60% | 50% | 40% | 30% | 20% | 10% |\n\n1 A student carries out an investigation to compare the reactivities of four metals, aluminium, copper, zinc and M.  \nHe adds strips of zinc to the aqueous solutions of the nitrates of each metal.
