As the specific gravity of calcium chloride brine increases, what happens to the density?

The specific gravity of a solution is a measure of its density compared to that of water. As specific gravity increases, it indicates that the solution is denser than water. Therefore, when the specific gravity of calcium chloride brine increases, the density of the brine also increases. This is because the addition of calcium chloride to water increases the mass of the solution without significantly increasing its volume, leading to a higher density.

Additionally, with calcium chloride brine, as more solute (calcium chloride) is dissolved in the water, the overall mass of the solution increases. Consequently, this results in a greater density. Understanding this relationship between specific gravity and density is important for applications in refrigeration systems, where the properties of brine solutions can affect their performance in heat transfer and freezing processes.

Thus, the correct understanding is that with an increase in specific gravity, the density must also increase, aligning with the given information about the properties of solutions.
