Types of Reactions : Metals with dilute acids

Most metals will react with dilute acids to give a salt and hydrogen gas.

Reaction I

Reaction I

Metal + acid arrowsalt + Hydrogen gas

 

Reaction II

Reaction II

 

In these reactions the metal replaces the hydrogen. Hydrogen gas is liberated (this is shown by the arrow pointing upwards). The other product is a salt which is formed from the chemical bonding of a metal with a non-metal component.

You will notice that the type of salt produced depends on the acid used.

Note:

  • Dilute acid will have no effect on copper. Copper is not reactive enough to replace the hydrogen in this type of reaction.

  • Sodium and potassium are far too reactive to use safely in the laboratory as the metal reactant.

 

Types of Reactions : Metal oxides with dilute acids

Metals oxides will react with dilute acids to give a salt and water.

Reaction I

Equation 3

metal oxide + acid arrow salt + water

Reaction II

Equation 4

 

The metal replaces the hydrogen. The two products are salt and water.

You will notice that the type of salt produced depends on the acid used.

 

Types of Reactions : Metal hydroxides with dilute acids

Metals hydroxides will react with dilute acids to give a salt and water.

Reaction I

Reaction 5

metal hydroxide + acid arrow salt + water

Reaction II

Reaction 6

 

The metal replaces the hydrogen. The two products are salt and water.

These reactions are examples of neutralisation.

You will notice that the type of salt produced depends on the acid used.

 

Types of Reactions : Metal carbonates with dilute acid

Metals carbonates will react with dilute acids to give salt, water and carbon dioxide gas.

Reaction I

Reaction 7

equation

 

Reaction II

Reaction 8

 

The metal replaces the hydrogen. The products are salt, water and carbon dioxide gas.

You will notice that the type of salt produced depends on the acid used.
