Measuring the pH of Isotonic Buffer Saline

In hospitals, intravenous (IV) solutions, such as saline or prescription drugs are commonly administered to patients for various therapies. IVs are used to deliver medications, replace fluids, balance electrolytes, and many other treatments. Since the solutions are introduced directly into the blood stream, the more similar in ionic strength the solutions are to the blood,…
