In addition, the last of the alum had to be removed from the beaker by rinsing the beaker, but some adhered to the wall of the beaker and could not be removed, slightly lowering the yield. (1) If the product had not been dry upon weighing, the yield would appear greater than it was, due to the extra mass of the liquid portion. However, the yield would actually
