Write down the reaction equations sodium-sodium hydroxide-sodium nitrate-nitric acid-copper (2) nitrate-copper (2) hydroxide

1. Sodium is an active alkali metal, easily reacts with water, forming alkali – sodium hydroxide – and hydrogen.

2Na + 2H2O = 2NaOH + H2.

2. Alkalis react with acids to form salts and water. In the reaction between sodium hydroxide and nitric acid, sodium nitrate and water are formed.

NaOH + HNO3 = NaNO3 + H2O.

3. To obtain nitric acid from sodium nitrate, it is necessary to carry out the reaction of nitrate with concentrated sulfuric acid while heating. Sodium hydrogen sulfate and nitric acid are formed.

NaNO3 + H2SO4 conc = NaHSO4 + HNO3.

4. Let’s compose the equation of the reaction between nitric acid and copper (II) hydroxide, copper (II) nitrate and water are formed.

2HNO3 + Cu (OH) 2 = Cu (NO3) 2 + 2H2O.

5. To obtain copper (II) hydroxide from copper nitrate, we will compose the equation of the reaction between salt and alkali – sodium hydroxide.

Cu (NO3) 2 + 2NaOH = Cu (OH) 2 + 2 NaNO3.
