Ion charges: (Na^+, Cu^2+, OH-,
`NO_(3-)`

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

Answer 1

Cu(NO₃)₂ + 2NaOH → Cu(OH)₂ + 2NaNO₃

Step-by-step 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⁻
