Question

2. NaOH +FeСl2 →.........................................

Answer 1

FeCl2 + 2NaOH → Fe(OH)2 + 2NaCl

Answer 2

The chemical reaction between sodium hydroxide (NaOH) and iron(II) chloride (FeCl2) can be represented as follows:

2 NaOH + FeCl2 → Fe(OH)2 + 2 NaCl

In this reaction, sodium hydroxide reacts with iron(II) chloride to produce iron(II) hydroxide and sodium chloride as the products. Iron(II) hydroxide is a greenish precipitate that can further oxidize to form brown-colored iron(III) hydroxide in the presence of air.
