PartA: Preparation of Nitrogen Monoxide 5. Insert the plunger into the syringe with the tip of the plunger touching the vial cap, and draw about 4 cm of acidified Feso 4 aq) into the syringe 6. Cap the syringe immediately
Part A: Preparation of Nitrogen Monoxide 5. Insert the plunger into the syringe with the tip of the plunger touching the vial cap, and draw about 4 cm3 of acidified FeSO4 (aq) into the syringe. 6. Cap the syringe immediately
Part A: Preparation of Nitrogen Monoxide 7. Shake the syringe gently to mix the NaNO(s)and the acidified FeSoalaq) To prevent the reaction from going too fast, you should stop shaking when the reaction goes. Only when the reaction stops or goes slowly should you shake the syringe again In case the amount of the nitrogen monoxide gas generated is more than the syringe can contain, let the plunger move out of the syringe(but with your hand holding the plunger to avoid falling) and allow excess gas to escape from the syringe
