Zn + H2SO4

The reaction between zinc (Zn) and sulfuric acid (H₂SO₄) is a well-known single displacement reaction. In this reaction, zinc displaces hydrogen from sulfuric acid, resulting in the formation of zinc sulfate (ZnSO₄) and hydrogen gas (H₂).

The balanced chemical equation for this reaction is:

\[ \text{Zn} + \text{H}_2\text{SO}_4 \rightarrow \text{ZnSO}_4 + \text{H}_2 \]

Description of the Reaction

1. Reactants:

   • Zinc (a solid metal)
   • Sulfuric acid (a strong acid in aqueous solution)

2. Products:

   • Zinc sulfate (an aqueous salt)
   • Hydrogen gas (which is produced as bubbles)

Reaction Type

• Single Displacement Reaction: In this type of reaction, an element reacts with a compound and displaces another element from it.

Observations

• You may observe bubbles of hydrogen gas forming during the reaction.
• Zinc sulfate will be in an aqueous solution after the reaction, which may be colorless.

Safety Considerations

• When carrying out this reaction, it is important to wear safety goggles and gloves, as sulfuric acid is highly corrosive and can cause burns.

This reaction is commonly used in laboratory settings to demonstrate the properties of metals and their interactions with acids.
