It is expressed by the chemical formula of iron sulfate caustic soda

Caustic soda (sodium hydroxide) with the chemical formula NaOH. A strong alkali with strong corrosiveness, generally in the form of flakes or granules, easily soluble in water (exothermic when dissolved in water) and forms an alkaline solution, and deliquescent, easy to absorb water vapor (deliquescent) and carbon dioxide (deterioration) in the air. NaOH is one of the essential chemicals in chemical laboratories and one of the common chemicals.

Pure products are colorless and transparent crystals. Density. Melting point.

Boiling point 1390 . Industrial products contain small amounts of sodium chloride and sodium carbonate, which are white opaque crystals. There are blocks, sheets, granules and rods, etc.

Sodium hydroxide can be used as an alkaline cleaning agent in water treatment, soluble in ethanol and glycerol; Insoluble in propanol, ether. It also has a corrosive effect on sodium carbon at high temperatures. It disproportionates with halogens such as chlorine, bromine, and iodine. It neutralizes with acids to form salt and water.

Iron sulphate with the chemical formula Fe2(SO4)3. Off-white powder or orthorhombic prismatic crystalline flowing pale yellow powder. Sensitivity to light.

Easily hygroscopic. It dissolves slowly in water, but dissolves quickly when there is a trace of ferrous sulfate in water, slightly soluble in ethanol, almost insoluble in acetone and ethyl acetate. Hydrolyzed slowly in aqueous solution.

The iron element in iron sulfate is +3 valence, sulfate is -2 valence, and its chemical formula is Fe2SO4 caustic soda is the common name of sodium hydroxide, sodium element is +1 valence, hydroxide is -1 valence, and its chemical formula is NaOH

So the answer is: Fe2SO4

By the representation of atoms, an atom is represented by an element symbol, and a number of such atoms are represented by a corresponding number in front of its element symbol, so the iron atom can be reserved for expression: fe

By the way the molecule is noted, the chemical formula of the substance is correctly written, and the corresponding number is added before the chemical formula, then the oxygen molecule can be represented as the slag as follows: Ul roll quietly o 2

The element symbol for the element sulfur is: s

So the answer is: fe; o 2 ；s．

Fe2(SO4)3 iron sulfate chemical formula.

Fe2(SO4)3:2 and 3 are the corner markers on the lower right.

Chemical formula of iron sulfate: Fe2(SO4)3

Among them, the numbers are all lower corner markers, and FE is the positive trivalent.

The chemical formula of iron sulfate: Fe2(SO4)3 where the numbers are all lower corner markers, and Fe is positive trivalent.

The chemical formula of ferrous sulfate: FeSO4, Fe is positive bivalent.

Fe2(SO4)3 SO4 ions have strong oxidizing properties, and Fe ions are the most ** state.

Fe2(SO4)3 This is iron sulfate.

Feso4 This is ferrous sulfate.
