Ion charges: (Na^+, Cu^2+, OH-, [tex]NO_{3-}[/tex]

Write a balanced chemical equation for the change you observed in the laboratory

Answer:



Note that the reaction in this experiment is:

Copper (II) nitrate + sodium hydroxide → copper (II) hydroxide +sodium nitrate

Respuesta :

Answer:

Cu(NO₃)₂  +  2NaOH  →  Cu(OH)₂  +  2NaNO₃

Explanation:

This is the reaction:

Cu(NO₃)₂  +  2NaOH  →  Cu(OH)₂  +  2NaNO₃

Let's verify the ions charges

Cu(NO₃)₂  →  Cu²⁺ + 2NO₃⁻

NaOH  →  Na⁺ + OH⁻

Cu(OH)₂  → Cu²⁺  +  2OH⁻

NaNO₃  →  Na⁺  +  NO₃⁻
