The chemical equation of the reaction between iron powder and dilute sulfuric acid is: The reaction phenomenon was that the solid slowly dissolved, bubbles were produced, and the solution gradually turned from colorless to light green. The resulting gas could burn, and when it burned, it produced a light blue flame. The reasons for this phenomenon were as follows: - Solid slowly dissolving: Iron will react with diluted sulfuric acid. Iron atoms will enter the solution and combine with sulfuric acid ions, causing the solid iron to gradually decrease, so the solid will slowly dissolve. - Air bubbles: During the reaction process, hydrogen gas (H <2>) is generated. The hydrogen gas escapes in the form of gas, so bubbles will be seen. - The solution gradually turned from colorless to light green: iron reacted with dilute sulfuric acid to form FeSO2. The solution of FeSO2 was light green. As the reaction progressed, the concentration of iron ions in the solution increased, and the color gradually turned light green. - The generated gas can burn, and when it burns, it produces a light blue flame. The generated hydrogen is flammable, and when it burns in the air, the flame is light blue. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
