| Write a molecular and ionic-molecular equation for the chemical reaction that occurs when aqueous solutions of iron (3) chloride and sodium hydroxide interact
Let’s compose the molecular equation of the reaction:
Iron chloride (lll) + sodium hydroxide we get iron hydroxide (lll) + sodium chloride
FeCl3 + 3NaOH = Fe (OH) 3 + 3NaCl
FeCl3 – soluble
3NAOH – soluble
Fe (OH) 3 is insoluble, which means it falls out as a residue, therefore it does not decompose into ions
3NaCl – soluble
Now let’s make a complete ionic-molecular equation:
Fe3 + + 3Cl- + 3Na + + 3OH- = Fe (OH) 3 + 3Na + + 3Cl-
Therefore, we get a short ionic-molecular equation:
Fe3 + + 3OH- = Fe (OH) 3
