Question

What's the product of reacting calcium chloride with iron III chloride?

Answer 1

Answer:

The balanced equation for the reaction between FeCl3 and NaOH is FeCl3 + 3NaOH -> Fe(OH)3 + 3NaCl. Since iron(III) chloride and sodium chloride are soluble in water, but not iron(III) hydroxide, the reaction causes a solid to be precipitated. As iron(III) hydroxide is brown, a brown precipitate is formed. Hence, this is known as a precipitation reaction.
