Question

С какими веществами реагирует NaOH: SO2, H2SO4, H2O, SO3, CaO, FeCl2, Cu(NO3)2, K2SO4, Fe(OH)3 по возможности уравнение реакции

Answer 1

 2NaOH+SO2=Na2SO3+H2O
2NaOH+H2SO4=Na2SO4+2H2O
2NaOH+SO3=Na2SO4+H2O
FeCl2+2NaOH=Fe(OH)2+2NaCl
2Cu(NO3)2+2NaOH=Cu(OH)2+2NaNO3
Fe(OH)3+3NaOH=Na3FeO3+3H2O

Answer 2

Reactivity of NaOH with Various Substances

NaOH (sodium hydroxide) is a strong base and can react with various substances. Let's explore its reactivity with the given substances:

1. SO2 (sulfur dioxide): - NaOH + SO2 → Na2SO3 + H2O 2. H2SO4 (sulfuric acid): - 2NaOH + H2SO4 → Na2SO4 + 2H2O 3. H2O (water): - NaOH can dissociate in water to form Na+ and OH- ions, but it does not undergo a chemical reaction with water itself.

4. SO3 (sulfur trioxide): - NaOH + SO3 → Na2SO4 5. CaO (calcium oxide): - CaO + 2NaOH → Na2Ca(OH)4 6. FeCl2 (iron(II) chloride): - FeCl2 + 2NaOH → Fe(OH)2 + 2NaCl 7. Cu(NO3)2 (copper(II) nitrate): - Cu(NO3)2 + 2NaOH → Cu(OH)2 + 2NaNO3 8. K2SO4 (potassium sulfate): - No specific reaction information found in the search results.

9. Fe(OH)3 (iron(III) hydroxide): - Fe(OH)3 + 3NaOH → NaFe(OH)4 [[2]](https://biblioteka.sibsau.ru/pdf/izdv/izdv_sibgtu/Finogenko_Khimiya_2019.pdf)

Conclusion

NaOH can react with a variety of substances, producing different products depending on the specific reaction. It is important to consider the specific reaction conditions and stoichiometry when predicting the products of these reactions.
