I'm assuming this reaction takes place in an aqueous solution...

This is a double replacement reaction...NaCl will remain dissolved in water, whereas Fe(OH)3 should be the one to precipitate.

Sodium is like pottasium because all common sodium salts are soluble in water. You know NaOH and FeCl3 are both soluble, so the only two choices are Fe(OH)3 and NaCl. NaCl is table salt and that is soluble, so the precipitate must be Fe(OH)3.

3 NaOH (aq) + FeCl3 (aq) ---> 3 NaCl (aq) + Fe(OH)3 (s)
