The sand mold is usually done in two halves, where one side of the mold is made with one pattern and another side is made using the other pattern (shown in Figure 1). While the molds may not always be in two halves, this arrangement provides the easiest method of both creating the mold and accessing the part, once cast. The top part of the mold is known as the "cope" .

To make bromine in the laboratory we need to find a chlorine source and react it with a solution of bromide ions. After formation of the bromine it must be separated from the solution in a suitable way. All this requires thinking and planning which, besides the procedural aspects involves other questions that will be discussed later. Let us now examine how such a system can be built to include ...
