The experiment was separation of the components of a mixture. I am trying to find the percentage recovery, when separating the mixture. The mixture that was used, was ammoinum chloride, sodium chloride and sand. The mixture was decanted twice with water. The NaCl was heated to evaporate the water. If the NaCl is not completely dried, how will it affect my percentage recovery?
