Which amongst the metals: Sodium, Aluminum, Magnesium, Calcium, Copper does not react even with steam

Open in App

Solution

Sodium reacts with cold water to form Sodium hydroxide and Hydrogen gas.
The reaction is shown below.
$2 Na (s) + 2 H_{2} O (l) \to 2 NaOH (aq) + H_{2} (g) + Heat Sodium hydroxide$
Aluminium reacts with steam to form Aluminium Oxide and Hydrogen gas.
The reaction is shown below.
$2 Al (s) + 3 H_{2} O (g) \to {Al}_{2} O_{3} (s) + 3 H_{2} (g) Aluminium Oxide$
Magnesium reacts with steam to form Magnesium oxide and Hydrogen gas.
The reaction is shown below.
$Mg (s) + H_{2} O (g) \to MgO (s) + H_{2} (g) Magnesium oxide$
Calcium reacts with cold water to form Calcium hydroxide and Hydrogen gas.
The reaction is shown below.
$Ca (s) + 2 H_{2} O (l) \to Ca {(OH)}_{2} (aq) + H_{2} (g) Calcium hydroxide$

Different metals react with water under different conditions. Copper is a metal that even does not react with water in the form of steam.
No reaction even with steam and at red heat.
$Cu (s) + H_{2} O (l) \to No reaction Copper$
Hence, Copper does not react even with steam.
