The equation CuSO4 + Na2HPO4 -> CuHPO4 + Na2SO4.

Detailed information about the reaction CuSO₄ + Na₂HPO₄ -> CuHPO₄ + Na₂SO₄:

• The above chemical equation describes the reaction between copper sulfate (CuSO₄) and sodium hydrophosphate (Na₂HPO₄) to produce copper hydrophosphate (CuHPO₄) and sodium sulfate (Na₂SO₄).
• This is an ion exchange reaction.

Reaction conditions:

• The standard conditions of this reaction are usually at room temperature and standard pressure.
• Copper sulfate and sodium hydrophosphate need to be in solution so that ions can move and react with each other.

Reaction process:

• When both substances are mixed together in solution, the copper ion (Cu₂+) from copper sulfate reacts with the hydrophosphate ion (HPO₄₂-) from sodium hydrophosphate to form copper hydrophosphate.
• Similarly, the sodium ion (Na+) from sodium hydrophosphate reacts with the sulfate ion (SO₄₂-) from copper sulfate to form sodium sulfate.

Phenomena occurring:

• During the reaction, there may be a precipitation phenomenon due to the formation of copper hydrophosphate, a substance that is insoluble in water.
• In addition, the color of the solution may also change due to the formation of new ions.
