Write the reaction equation: Na- NaOH- Cu (OH) 2- CuO- CuSO4
| September 5, 2021 | education
We obtain the following reaction equations, which correspond to the given chain of transformations: Na → NaOH → Cu (OH) 2 → CuO → CuSO4
1) 2Na + 2H2O → 2NaOH + H2 ↑ (substitution reaction);
2) 2NaOH + Cu (NO3) 2 → Cu (OH) 2 + 2NaNO3 (exchange reaction);
3) Cu (OH) 2 → CuO + H2O (decomposition reaction);
4) CuO + H2SO4 → CuSO4 + H2O (exchange reaction).
