Select the proper word equation to express the following chemical reaction: 3NaOH (aq) + Fe(NO3)3 (aq) arrow Fe(OH)3 (s) + 3NaNO3 (aq) Sodium hydroxide (III) solution reacts with iron nitrate solution to produce a precipitate of iron (III) hydroxide in a solution of sodium nitrate. Aqueous solutions of sodium hydroxide and iron (III) nitrate react to produce a precipitate of iron (III) hydroxide in an aqueous solution of sodium nitrate. Sodium hydroxide solution reacts with iron nitrate solution to produce a precipitate of iron hydroxide in a solution of sodium nitrate.

Champion:

See, NaOH is sodium hydroxide and it's in an aqueous solution, FeNO3 is Iron(III) nitrate because iron is showing a valency factor of 3 here. The other thing to notice is that Iron (III) hydroxide is formed in solid state and hence it will precipitate.
