Reaction equation: KOH-Zn OH 2-K2ZnO2-ZnSO4 Na-NaOH-Fe OH 3-Fe2O3

| May 7, 2021 | education

We write down the reaction equation for the next chain.
KOH – ZnOH2 – K2ZnZO2 – ZnSO4.
KOH + ZnSO4 = K2SO4 + Zn (OH) 2.
When potassium hydroxide and zinc sulfate react, potassium sulfate and zinc hydroxide are formed.
Zn (OH) 2 + 2KOH = K2ZnO2 + 2H2O.
When zinc hydroxide and potassium hydroxide react, potassium zincate and water are formed.
К2ZnO2 + 2H2SO4 = K2SO4 + ZnSO4 + 2H2O.
When potassium zincate and sulfuric acid react, potassium sulfate, zinc sulfate and water are formed.
Na – NaOH – FeOH3 – Fe2O3.
2Na + 2H2O = 2NaOH + H2.
When sodium and water interact, sodium hydroxide is formed and hydrogen is released.
3NaOH + FeCl3 = Fe (OH) 3 + 3NaCl.
When sodium hydroxide and ferric chloride react, ferrous hydroxide and sodium chloride are formed.
2Fe (OH) 3 = Fe2O3 + 3H2O.
Iron hydroxide decomposes into iron oxide (lll) and water.
