Conductivity of an acidic solution is generally related to the concentration of hydrogen ions (H⁺) in the solution. The lower the pH, the higher the concentration of H⁺ ions, and consequently, the higher the conductivity.
Based on the pH values provided:
- HA (pH 5.6) has the least H⁺ ions and will be the least conductive.
- HC (pH 4.7) has a higher concentration of H⁺ ions than HA but less than HB.
- HB (pH 3.9) has the highest concentration of H⁺ ions and will be the most conductive.
Thus, the order from least conductive to most conductive is:
HA, HC, HB
So the correct response is:
HA, HC, HB
