The conductivity of an acid solution is influenced by the concentration of hydrogen ions (H⁺) in the solution. The lower the pH, the higher the concentration of H⁺ ions, which leads to greater conductivity.
Given the pH values of the acids:
- HA: pH 5.6
- HC: pH 4.7
- HB: pH 3.9
We can deduce the following order of acidity (and therefore conductivity) from least to most conductive:
1. HA (pH 5.6 - least H⁺)
2. HC (pH 4.7 - moderate H⁺)
3. HB (pH 3.9 - most H⁺)
Therefore, the order from least conductive to most conductive is:
**HA, HC, HB.**
