What is the reaction formula for preparing ferrate?The preparation of ferrate mainly has the following reaction formula and its meaning:
1. ** wet preparation **
- The reaction formula is [2FeO4 ^{2-}+3ClO ^-+4OH^- = 2FeO4 ^{2 -}+3ClO ^-+5H2O'].
- This reaction formula shows that under basic conditions, the reduction reaction of iron (Fe(OH)_3) and the reduction reaction of iron (ClO^-) occurs. The iron element in the iron dioxide was oxided, increasing from the valency of [+3] to the valency of [+6], forming ferrate ions [(FeO4 ^{2 -})], while the Cl-element in the Cl-ion was reduced from the valency of [+1] to the valency of [-1], forming Cl-ion [(Cl4-)]. At the same time, the reaction required the participation of the hydrogen ion, which formed water.
2. ** Dry preparation **
- The reaction formula is [2FeSO4 + 6Na2O2 = 2Na2FeO4 + 2Na2O +2Na2SO4 + O2].
- In this reaction, the iron element in FeSO4 is dissolved in Na2SO2. Oxidation of ((Na2O2), Iron increases from +2 to +6 to form ferrate.((Na2FeO4)); part of the oxygen element in the sulfur dioxide decreased from the valency of <-1> to the valency of <-2>, and the other part of the oxygen element increased from the valency of <-1> to the valency of <0> to form oxygen <((O2)>, and at the same time, it formed sulfur dioxide <((Na2O)> and sulfur dioxide <(Na2SO4)>.
3. ** Preparing Ferrate from Ferrate **
- In the industry, the first step was to produce the solution of ferrate, and then at a low temperature, a certain amount of potassium ferrate could be added to the solution of ferrate to produce the solution of ferrate. The reaction principle was based on the double decomposition reaction. The ion reaction was 4FeO4 ^{2 -}+10H2O = 4Fe0H (Ox) 3 (colloid)+3O21 + 8Kh21, and the chemical equation was 4K2FeO4 + 10H2O = 4Fe0H (Ox) 3 (colloid)+3O21 + 8Kh21). This reaction showed that when the ferrate reacted with water, the ferrate ions would be digested to form iron colloid, oxygen, and hydrogen ions, reflecting the chemical properties of the ferrate in water. In this reaction, the valency of the iron element did not change. There was also the reaction of dry method of producing ferrate,[2FeClO +4NaOx = 2Na2FeO4 + 5H2O +3NaClO]. This reaction indicated that iron was oxified by hypochlor under an acidic condition to produce ferrate, chlor, and water. This was a way to produce ferrate and then ferrate.

Light up the futureThe lyrics of " Light Up the Future " were as follows:
I see the sky clear, and the light falls,
Sea gulls in the blue sea, flying freely,
Every ship had a direction.
They sailed happily into the distance.
I see the earth blooming, green hope,
Sunflower smiled and stared at the sun.
Every blade of grass was working hard to grow.
He was determined to head in the direction of the sky.
I see a light, lighting up the dawn,
Happiness is having you by my side,
Give me wings to fly to the distance of hope,
The voice in her heart said, I want to be like you.
I have a light that brightens the future,
With you, there will be warmth and sweet dreams.
Hand in hand, passing beauty and strength,
Endless hope would pass through time.
