The equation Fe(NO3)2 + Ca(OH)2 -> Ca(NO3)2 + Fe(OH)2

  1. Detailed information about the chemical equation: Fe(NO3)2 + Ca(OH)2 -> Ca(NO3)2 + Fe(OH)2

The above equation is an ion exchange reaction. In this reaction, the nitrate ion (NO3-) from Fe(NO3)2 and the hydroxide ion (OH-) from Ca(OH)2 are exchanged, resulting in the formation of Ca(NO3)2 and Fe(OH)2.

  1. Reaction conditions

For the reaction to occur, sufficient temperature and pressure are needed. In addition, Fe(NO3)2 and Ca(OH)2 need to be in a water environment for ions to be able to move and interact with each other.

  1. Reaction process

When Fe(NO3)2 and Ca(OH)2 are mixed together in a water environment, the nitrate and hydroxide ions begin to move and interact with each other. The new chemical compound is formed due to the ion exchange between the two initial compounds.

  1. Occurring phenomena

When the reaction occurs, there will be a color change due to the formation of Fe(OH)2, a brown solid. If the reaction is carried out in a test tube, you can also see the precipitation of Fe(OH)2 appearing.
