Which formula is correct for calculating the strength of a solution?

• A. Concentration x Fluid Volume = Solution Strength
• B. Index x Fluid Volume = Solution Strength x Total Volume
• C. Solution Strength = Fluid Volume / Total Volume
• D. Fluid Volume + Total Volume = Index

Answer: (B)

To understand why the selected option is correct, it's important to recognize how the various components interact to determine the strength of an embalming solution. The formula states that the Index (which indicates the concentration of formaldehyde in the embalming fluid) multiplied by the fluid volume contributes to the overall solution strength when total volume is also taken into consideration.

In embalming, the strength of a solution is defined by how concentrated it is relative to the total volume that is being utilized. This means that when you multiply the index, which is a measure of the potency of the fluid, by the amount of fluid being used, you are effectively calculating the total amount of active ingredient available within that fluid volume. Adjusting for total volume also accounts for any dilution effects that may occur when the solution is mixed with other components, such as water or pre-existing bodily fluids.

This comprehensive approach allows embalmers to ensure they are using a solution that will achieve the desired preservation effect, leading to proper embalming practices. The other choices do not accurately represent the relationship between these variables, as they either improperly balance the equation or fail to establish the connection between these important elements, leading to misunderstandings about how to compute solution strength in practical applications of embalming.
