Chemical Properties of Metals

Definition

We can distinguish them properly by following reactions

Metals and Oxygen

Metal + Oxygen → Metal Oxide +

• Metal oxides are basic in nature.
• Some are Amphoteric Oxides.

Metal and Water

Metal Oxide + Water → Metal Hydroxide

Metals react with water in different states

• Sodium, Potassium - Cold Water
• Calcium - Cold Water and starts floating due to Hydrogen gas sticking to the surface.
• Magnesium - hot water
• Aluminium, Iron, Zinc - Steam

Metal and Acid

Metal + Acid → Metal Salt +

Loophole with HNO3

Reaction with this acid does not produce gas. Why? Because it is a good oxidising agent and forms water with the hydrogen molecule. It itself gets reduced to Nitrogen Oxides

Aqua Regia

The homogenous mixture of Conc. and Conc. in the Ratio of 1:3

Metal with Salt Solutions of Other Metals

Well, the metal with higher reactivity would displace the metal in the salt solution For example,

Flashcards

Metals and their reactions with different states of water: ?

• Sodium, Potassium - Cold Water
• Calcium - Cold Water and starts floating due to Hydrogen gas sticking to the surface.
• Magnesium - hot water
• Aluminium, Iron, Zinc - Steam

How do metals react with oxygen and then in water? ?

• Metal + Oxygen → Metal Oxide +
• Metal Oxide + Water → Metal Hydroxide

Why is Hydrogen gas not produce when metal reacts with HNO3? ? Because it is a good oxidising agent and forms water with the hydrogen molecule. It itself gets reduced to Nitrogen Oxides

Aqua Regia is the {{mixture of and in the Ratio of 1:3}}
