Final answer:
Electrolyte B, with a specific gravity of 1.125, likely has more active ingredient than Electrolyte A, which has a specific gravity of 1.015, because a higher specific gravity suggests a higher density of ions and thus a higher concentration of the active ingredient.
Step-by-step explanation:
When comparing electrolyte A with a specific gravity of 1.015 and electrolyte B with a specific gravity of 1.125, it is evident that electrolyte B has a higher specific gravity and thus a higher density compared to electrolyte A. Specific gravity, as mentioned, is the ratio of the density of a substance to the density of pure water at the same conditions.
A higher specific gravity usually indicates a higher concentration of the active ingredient in the electrolyte solution. Based on the specific gravity data provided, which shows that electrolyte B has a higher specific gravity, we can infer that electrolyte B contains more active ingredient compared to electrolyte A.
This conclusion is supported when considering the conductivity of electrolytes. Typically, strong electrolytes, which dissociate completely into ions, have higher conductivities.
The density of ions directly affects conductivity, and since the specific gravity is an indicator of density, a higher specific gravity in electrolyte B suggests more ions are present, therefore more active ingredient.
