Equation for Copper Sulphate and Sodium Hydroxide?

When copper sulfate (CuSO₄) reacts with sodium hydroxide (NaOH), it forms copper(II) hydroxide (Cu(OH)₂) and sodium sulfate (Na₂SO₄).

The balanced chemical equation for this reaction is:

CuSO4​(aq)+2NaOH(aq)→Cu(OH)2​(s)+Na2​SO4​(aq)

In this reaction:

• Copper sulfate (CuSO₄) is dissolved in water.
• Sodium hydroxide (NaOH) is also in solution.
• Copper(II) hydroxide (Cu(OH)₂) precipitates as a blue solid.
• Sodium sulfate (Na₂SO₄) remains in solution.

This is an example of a double displacement reaction, where the copper ions (Cu²⁺) combine with hydroxide ions (OH⁻) to form a precipitate of copper(II) hydroxide.
