When crystals of feso4 are strongly heated the residue obtained is?
The residue obtained from heating crystals of FeSO4 (iron(II) sulfate) is Fe2O3 (iron(III) oxide) and SO2 (sulfur dioxide) gases. This is because the heating process causes the iron(II) sulfate to decompose, releasing water vapor, sulfur dioxide gas, and leaving iron(III) oxide as a solid residue.
What is chemical name for FeSO4?
Iron (II) sulfate is the correct name for this compound. The Fe ion has a charge of 2 and so does the sulfate ion, so there is no subscript after them.
Can Fe be decomposed by a chemical change?
Yes, ferrous sulfate (Fe) can be decomposed by a chemical change into iron oxide and sulfur dioxide. This process typically involves heating the compound to facilitate the decomposition reaction.
What does feSO4 stand for?
FeSO4 stands for iron (II) sulfate, which is a chemical compound composed of iron, sulfur, and oxygen. It is commonly used in various industrial applications and as a dietary supplement for iron deficiency.
What is the name for Fe(SO4)3?
Fe(SO4)3 is Iron(III) sulfate Wrong: Fe2(SO4)3 is iron(III) sulfate.
What is FeSO47H2O?
That would be: Iron (II) Sulfate, with Heptahydrate, believe.
What name is FeSO4.7H2O?
The name of FeSO4•7H2O is iron(II) sulfate heptahydrate.
What is the calculation for the formula FeSO4.7H2O?
The molar mass of iron(II) sulfate heptahydrate is 278,01556.
What color is FeSO4.3H2O?
FeSO4.3H2O, also known as iron(II) sulfate heptahydrate, is a greenish compound.
What is the formula for Iron II sulfate heptahydrate?
The chemical formula for iron(II) sulfate heptahydrate is FeSO4•7H2O.
How make ferrous sulphate?
To make ferrous sulfate, also known as iron(II) sulfate, start with iron filings or iron sulfate heptahydrate crystals. Dissolve the iron source in sulfuric acid and oxidize it to form ferrous sulfate solution. Then, crystallize the solution to obtain solid ferrous sulfate crystals.
What is the color of iron II sulphate?
Iron II sulfate is typically pale green in color when hydrated and light green or white when anhydrous.
What is the colour of iron ii sulphate?
Bluish-green (I personally would call it aquamarine or possibly teal). The link shows a picture of (solid) iron (II) sulfate heptahydrate, which is the same shade as the solution would be.
How do you make iron sulfate hydroxide and oxide?
To make iron sulfate, mix iron oxide with sulfuric acid. For iron hydroxide, mix iron sulfate with a strong base like sodium hydroxide to precipitate out the iron hydroxide. Iron oxide can be made by heating iron metal in the presence of oxygen.
Is iron sulphate a hydrated salt?
Yes, iron sulfate is often found in a hydrated form, such as iron(II) sulfate heptahydrate (FeSO4•7H2O) or iron(III) sulfate nonahydrate (Fe2(SO4)3•9H2O). These hydrated forms contain water molecules within their structures.
How can make ferric sulphat?
To make ferric sulfate, you would typically start with iron sulfate, and then oxidize it to form ferric sulfate. This can be done by bubbling chlorine gas through a solution of iron sulfate, which will convert the iron(II) ions to iron(III) ions. Be cautious when working with chlorine gas, as it is toxic and should only be handled in a well-ventilated area.
Which substance turns black on heating in air?
Iron turns black on heating in air due to the formation of iron oxide, commonly known as rust.
