Question

Explain how you would prepare each of the following solutions, using liquid stock hydrogen peroxide as the solute and saline as the solvent

Section 3 Drug Dosage Calculations Review Set 27 plain how you would prepare each of the following solution as the solute and saline as the solvent. 1. 480 mL of strength for wound irrigation

Answer 1

Answer 1.

To find the strength of each solutions,

As the saline is the solvent

And out of the total solvent its 1/3 part is solute, that is hydrogen peroxide.

To find the exact volume of both the solute and the solvent from the given question.,

480 ml of 1/3 strength for wound irrigation.

480 ml X 1/3 = 160 ml.

The amount of solute ( hydrogen peroxide ) is 160 ml.

Out of 480 ml of total volume, 160 ml is hydrogen peroxide.

So, 480 ml - 160 ml = 320 ml saline as solvent.

Hence, 160 ml = Hydrogen peroxide.( solute)

& 320 ml = saline.( solvent ).

Total= 480 ml.
