Iron II compounds form a dark green precipitate when sodium hydroxide is added Why does the precipitate turn orange-brown when left standing?
The dark green precipitate formed when sodium hydroxide is added to iron II compounds is iron II hydroxide. When left standing, the iron II hydroxide undergoes further oxidation to form iron III hydroxide, which is orange-brown in color. This change in color is due to the conversion of iron II to iron III within the precipitate.
What are the products of iron II sulfate plus sodium hydroxide?
The products of the reaction between iron II sulfate and sodium hydroxide are iron II hydroxide and sodium sulfate. The balanced chemical equation for this reaction is FeSO4 + 2NaOH → Fe(OH)2 + Na2SO4.
What is the color of lead II hydroxide?
It has a white color in the form of powder of cyrstals : )
What is the colour change when sodium hydroxide is added to iron II sulphate?
dark green (but orange - brown if left standing)
What is the formula of Iron II hydroxide?
The formula for Iron(II) hydroxide is Fe(OH)2. It is an inorganic compound that consists of one iron(II) ion bonded to two hydroxide ions.

What are the two compounds formed when iron 2 sulphate is mixed with sodium hydroxide?
Iron (II) hydroxide and sodium sulfate are formed when iron (II) sulfate is mixed with sodium hydroxide. Iron (II) hydroxide is a green precipitate that forms in the reaction.
What is the mass in grams for 0.226 mole of Iron hydroxide?
It depends on whether it is iron (II) hydroxide or iron (III) hydroxide.
What is the percent of iron in iron (II) hydroxide?
Iron (II) hydroxide has a chemical formula Fe(OH)2. To find the percent of iron in iron (II) hydroxide, you need to calculate the molar mass of iron (Fe) and divide it by the molar mass of the compound Fe(OH)2, then multiply by 100 to get the percentage. The percent of iron in iron (II) hydroxide is approximately 69.9%.
What is the chemical name of FE OH 2?
The chemical name for Fe(OH)2 is iron(II) hydroxide.

What is the name for FeOH2?
Fe(OH)2 is named iron(II) hydroxide. It can also be named ferrous hydroxide.
How metallic hydroxide is formed when an iron is immersed in an acidic solution?
After the reaction of iron with an acid a salt is formed, not a hydroxide.
