Answer:
HCL
Explanation:
Since the question is requesting about acids only, strong acids is an acid that dissociate and ionized fully in water while a weak acid is an acid that does not dissociate completely and ionize fully in a solution. Generally, stronger acids are better conductors than weak acid because strong acid dissociate, ionize and produce more ions in the solution compared to weak acid. So for acids, the lower the pH, the higher the electrical conductivity.
However, strong bases are base that dissociate fully in water to produce ions too. Following similar trend the with acid but in this case, the higher the pH, the greater its electrical conductivity. So in respect to the question above, HCl > HNO₃ > H₂CO₃ > H₃BO₃ in terms of electrical conductivity while in the base section, KOH > NaOH and the rest
