Correct Option
The correct option is Aluminium, iron and zinc.
Explanation
The reactivity of metals with water depends on their position in the electrochemical series (reactivity series). Metals are classified based on whether they react with cold water, hot water, steam, or do not react at all. The reaction generally produces hydrogen gas and either a metal hydroxide or a metal oxide.
Analysis of Metal Reactivity
- Reaction with Cold Water: Highly reactive metals such as Potassium (K), Sodium (Na), and Calcium (Ca) react violently or vigorously with cold water to form metal hydroxides and hydrogen gas. Therefore, Sodium, potassium and calcium is incorrect.
- Reaction with Hot Water: Magnesium (Mg) does not react with cold water but reacts with hot water to form magnesium hydroxide and hydrogen.
- Reaction with Steam: Metals like Aluminium (Al), Iron (Fe), and Zinc (Zn) are not reactive enough to react with cold or hot water. However, they react with steam to form metal oxides and hydrogen gas. Therefore, Aluminium, iron and zinc is correct.
- No Reaction with Water: Metals such as Lead (Pb), Copper (Cu), Silver (Ag), and Gold (Au) do not react with water (cold, hot, or steam) at all. Therefore, options Lead, copper and silver and Gold, silver and platinum are incorrect.
Key Takeaway:
Aluminium, Iron, and Zinc react only with steam to form metal oxides and hydrogen. They do not react with liquid water (cold or hot). In contrast, alkali metals react with cold water, and noble metals do not react with water in any form.
