Whatis the chemical name of the substance formed in the slow reaction that takes place when iron filings are mixed with water?
Probably Fe2O3, iron(III) oxide. Rust is formed with oxygen from the air and moisture and usually is referred to in texts as hydrated iron(III) oxide.
The substance formed in the slow reaction when iron filings are mixed with water is called iron(II) hydroxide, or sometimes called ferrous hydroxide. It is a chemical compound consisting of iron atoms, oxygen atoms, and hydrogen atoms.
To determine the chemical name of the substance formed in the reaction, we need to understand the reaction itself. When iron filings (Fe) are exposed to water (H2O), a chemical reaction occurs, resulting in the formation of iron(II) hydroxide (Fe(OH)2) and molecular hydrogen gas (H2).
The balanced chemical equation for this reaction is as follows:
Fe + 2H2O -> Fe(OH)2 + H2
In this equation, Fe represents iron, H2O represents water, Fe(OH)2 represents iron(II) hydroxide, and H2 represents hydrogen gas.
So, to answer your question, the chemical name of the substance formed in the slow reaction when iron filings are mixed with water is iron(II) hydroxide.
