The copper sulfate is used as a decolorizing agent rather than water. The copper sulfate washes the purple primary stain out of the capsular material without removing the stain bound to the cell wall. At the same time, the decolorized capsule absorbs the copper sulfate, and the capsule will now appear white in contrast to the deep purple of the cell.

Explain the function of Copper Sulfate in the spore staining procedure?
From what i read in my book: Because the capsule is nonionic, unlike the bacterial cell, the primary stain adheres to the capsule without binding to it. Since the capsule is water- soulube, copper sulfate, rather than water, is used to wash the purple primary stain out of the capsular material without removing the stain that is bound to the cell wall.

What is the principle of capsule staining?
Bacterial capsules are composed of high-molecular-weight polysaccharides and/or polypeptides, and are associated with virulence and biofilm formation. Unfortunately, capsules do not stain well with crystal violet, methylene blue, or other simple stains. This unit describes two methods of capsule staining. The first is a wet-mount method using India ink; the capsule is visualized as a refractile zone surrounding a cell. The second is a direct-staining dry-mount method that precipitates copper sulfate and leaves the capsule as a pale blue zone. Both methods are easily performed within approximately 5 min.
