The chemical equation FeCl2 + 2KCN -> 2KCl + Fe(CN)2

  1. Detailed information about the equation FeCl2 + 2KCN -> 2KCl + Fe(CN)2
    This chemical equation describes the reaction process between iron(II) chloride (FeCl2) and potassium cyanide (KCN) to create potassium chloride (KCl) and iron(II) cyanide (Fe(CN)2).

  2. Reaction conditions
    This reaction requires appropriate temperature and pressure to occur. Normally, this reaction takes place under standard temperature and pressure conditions.

  3. Reaction process
    When FeCl2 comes into contact with KCN, it reacts with KCN to form KCl and Fe(CN)2. The reaction process takes place in the following mole ratio: 1 mole of FeCl2 reacts with 2 moles of KCN to produce 2 moles of KCl and 1 mole of Fe(CN)2.

  4. Observed phenomena
    When the reaction occurs, a change in color and the formation of precipitate can be observed. At the same time, there may also be changes in heat (either releasing or absorbing heat).
