Metals such as sodium, potassium, calcium, magnesium, and lithium react with oxygen to form a basic metal oxide. These metals react with dilute hydrochloric acid to form metal chloride and hydrogen gas. Unreactive metals, such as silver and gold, do not show a reaction with dilute acid.
Metals such as lithium, potassium, and calcium also react violently with water at room temperature. Zinc reacts with hot water to form zinc oxide and hydrogen gas. The reaction of iron or nickel with steam, results in the formation of metal oxide and hydrogen gas.
After completing this module, you will be able to:
- Describe the reaction of metals with oxygen.
- Describe the reaction of metals with dilute hydrochloric acid.
- Analyze the reaction of metals with water at various temperatures.
- Identify metals on the basis of their chemical properties.
