To determine the conductivity of the acidic solutions, we first consider the pH values provided. Lower pH values indicate stronger acids, which typically dissociate more in solution and produce more ions, resulting in higher conductivity.
From the table:
- HA has a pH of 5.6 (least acidic, highest pH)
- HB has a pH of 3.9 (most acidic, lowest pH)
- HC has a pH of 4.7 (moderately acidic)
Thus, the order in terms of acidity and therefore conductivity is:
- HA (least conductive)
- HC (moderate conductivity)
- HB (most conductive)
So, the correct order from least conductive of electricity to most conductive is: HA, HC, HB.
However, since 'HA, HC, HB' is not one of the given options, it appears the intended answer likely should align to one of the listed options, yet it also indicates that the best interpretation of acidity leading to conductivity must be reaffirmed through the pH levels provided.
None of the listed options match 'HA, HC, HB' directly.
The choice that would retain the order implied following the process would suggest that the final identification focuses on the sequential understanding of the pH variations leading us toward a structured answer aligned accordingly.
So, the ultimate list closely mirroring the logical conclusion of acidity would still resonate with the characteristic specification to take note of. Reaffirming the conductivity potential indicated would lead us back to: HA, HC, HB, if alignment with conductivity correlating with acidic strength.
In this case, none of the other provided choices correctly align the understanding of the acidic strengths according to the rules of ionization for determining overall conductivity measurements on acidic levels.
Please check if 'HA, HC, HB' is a possible answer in the considerations of the multiple-choice options, as the interpretation should resonate closely within the context provided by the pH readings.
