Final answer:
Strong acids and bases, also known as strong electrolytes, ionize almost completely in water, resulting in high electrical conductivity, unlike weak acids and bases, which are weak electrolytes with lower conductivity.
Step-by-step explanation:
When we consider the electrical conductivity of acids and bases in aqueous solutions, we look at the presence of ions, which facilitate the conduction of electricity. Strong acids and strong bases are called strong electrolytes because they ionize essentially completely in water, producing a large number of ions that result in high electrical conductivity.
Conversely, weak acids and weak bases, known as weak electrolytes, partially ionize in water and produce fewer ions, which leads to lower electrical conductivity. Therefore, the correct answer to which generally has better electrical conductivity is: a) Strong acids and bases.
