Streptomycin, an antibiotic, is produced on a large scale in the United States. The purified solution contains 50 wt% streptomycin water. Preparation of 500 mL intravenous (IV) drip solution bag requires addition of diluent and preservative. The diluent solution is 2 wt% NaCl in water. The preservative solution is 10 wt% diluent and 5 wt% NaCl in water. The final product, ready for packaging,contains 10 wt% streptomycin and 3% preservative.
(a) Sketch the IV drip bag preparation process, clearly identifying all variables of interest with an appropriate symbol and associated units.
(b) Develop an equation to determine the ratio of streptomycin solution to total solution.
(c) Develop an equation to determine the ratio of preservative solution to total solution.
(d) Develop an equation to determine the ratio of diluent solution to total solution.
(e) What is the NaCl content (wt%) in the final product?
