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

• A. It increases
• B. It decreases
• C. It remains constant
• D. It fluctuates

Answer: (A)

When discussing the relationship between specific gravity and density, it's crucial to understand what specific gravity represents. Specific gravity is a dimensionless quantity that compares the density of a substance to the density of a reference substance (typically water for solids and liquids). Since specific gravity is directly related to density, as the specific gravity of calcium chloride increases, it indicates that the mass of the substance per unit volume is also increasing. Density is defined mathematically as mass divided by volume. Therefore, if the specific gravity of calcium chloride increases, it signifies that the substance has more mass for the same volume, leading to an overall increase in density. This relationship helps us understand that compounds with a higher specific gravity will invariably have a higher density, taking into account that the reference substance remains constant. In summary, with a higher specific gravity indicating greater mass relative to volume, the density of calcium chloride indeed increases, confirming the correctness of the selected answer.
