Answer:
NaOH
Step-by-step explanation:
FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl
1:3:1:3
2 Moles FeCl3 and 4 Moles of NaOH
Ok so the ratio is 1:3 so we need 3 moles of NaOH for every mole of FeCl3
So we have 2 moles of FeCl3 so we would need 6 moles of NaOH but we only have 4 so NaOH is the limiting reagent.
