Regents Chemistry Exam June 2024 Question 46
46 Which solution is the best conductor of electricity?
(1) 0.0010 M CaCl2(aq)
(2) 0.010 M CaCl2(aq)
(3) 0.10 M CaCl2(aq)
(4) 1.0 M CaCl2(aq)
Solution:
When dissolved in water, ionic compounds can conduct electricity because they produce ions. The solution with the highest concentration is the best conductor of electricity because it produces the most ions. Choice 4 is the correct answer choice because it has the highest molarity.
