Question

A0.150 M sodium chloride solution is referred to as a physiological saline solution because it has the same concentration of salts as normal human blood. Describe the step by step procedure on how to prepare 450.0 mL of a physiological saline solution.

Answer 1

For example, to make 100 milliliters of normal saline solution, which is a 0.9% solution, you need nine grams of salt. If you need a pint of solution, you should add 2.9 tablespoons of salt. Measure the salt and add it to the water. Swirl the flask until all the salt is dissolved.
