Obtain approximately 0.1 g ferric chloride (FeCl3) provided in a vial or test tube. Using a graduated cylinder measure and add 4 mL of water to the ferric chloride in the vial. Shake until all the ferric chloride dissolves to give a clear yellow solution. Draw 1.0 mL of a liquid soap into a plastic pipette and add the liquid soap dropwise to the ferric chloride solution. Note the formation of a precipitate on the surface of the solution after a few drops of liquid soap have been added. Continue addition of all the remaining liquid soap with shaking. The white precipitate of iron(III) hydroxide, Fe(OH)3, settles on standing.
Observations Record appearance of precipitate:
1. Write the complete formula unit (molecular) equation for the reaction.
2. Write the complete ionic equation for the reaction.
3. Write the net ionic equation for the reaction
