Discussion and Conclusion - seperation of a mixture

Another method of physical separation that we used to separate the sand, salt, and iron mixture was filtration. Because the salt was soluble in water while the sand was not, we were able to filter out the majority of the salt and water from the solution and leave the sand behind, making it possible for us to find out the amount of sand that was ...
