Final answer:
The conductance of deionized water is lower than normal water because it lacks the ions necessary for conducting electricity. so, option b is the correct answer.
Step-by-step explanation:
The conductance of deionized water (water with no ions) should be lower than normal water. Normal water contains ions that facilitate the conduction of electricity. In contrast, deionized water lacks these ions, making it a poor conductor. Conductivity is dependent on the presence of freely mobile, charged species such as ions. Electrical conductance is greater in solutions with a higher concentration of ions, as seen in normal tap water, which typically contains dissolved minerals and electrolytes. Thus, deionized water, being free of these ions, exhibits much lower electrical conductivity.
Deionized water, which has no ions, has lower conductance than normal water. Water with ions, such as a solution of an ionic compound, conducts electricity well.
The conductance of deionized water (water with no ions) is lower than normal water. Distilled water, which is a type of deionized water, does not conduct electricity. On the other hand, water with ions, such as a solution of an ionic compound, conducts electricity well.
