The following substances are given: iron, chloride acid, sodium hydroxide. How, using only these substances, to obtain ferrum (II) hydroxide?

1) First, we get iron (II) chloride, which is formed by the interaction of metallic iron and hydrochloric acid:

Fe + 2HCl = FeCl2 + H2 ↑

2) And then we get iron (II) hydroxide by the reaction between iron (II) chloride and sodium hydroxide (sodium hydroxide):

FeCl2 + 2NaOH = Fe (OH) 2 ↓ + 2NaCl
