The end of the condenser is dipped into a known volume of standard ,acid, (i.e. ,acid, of known concentration). A weak ,acid, like boric ,acid, (H 3 BO 3) in excess of ammonia is often used.Standardized HCl, H 2 SO 4 or some other strong ,acid can, be used instead, but this is less commonplace. The sample solution is then distilled with a small amount of ,sodium hydroxide, (NaOH).
