The equation CuSO4 + NaOH -> Cu(OH)2 + Na2SO4

  1. Detailed information about the reaction CuSO4 + NaOH -> Cu(OH)2 + Na2SO4:

    • This is an ion-exchange reaction between copper(II) sulfate (CuSO4) and sodium hydroxide (NaOH), resulting in copper(II) hydroxide (Cu(OH)2) and sodium sulfate (Na2SO4).
    • To balance the equation, we need 2 molecules of NaOH for each molecule of CuSO4. Therefore, the balanced equation is: CuSO4 + 2NaOH -> Cu(OH)2 + Na2SO4.

  2. Reaction conditions:

    • The reaction occurs well at room temperature.
    • Copper(II) sulfate and sodium hydroxide need to be dissolved in water to form a solution before the reaction.

  3. The reaction process:

    • When dissolving copper(II) sulfate in water, we have a blue solution.
    • When adding NaOH solution to the CuSO4 solution, the solution will turn to azure due to the formation of Cu(OH)2.

  4. Occurrences:

    • When adding NaOH to the CuSO4 solution, the color of the solution changes from blue to azure due to the formation of Cu(OH)2.
    • Azure precipitate of copper(II) hydroxide will appear in the solution.
