Question

Kylie has two glasses with equal volumes of pure water. She adds 40 g of sugar to one of the glasses of water and 40 g of salt to the other. When sugar is dissolved in water, it does not change the number of ions present. When salt is dissolved in water, however, the number of ions significantly increases.
Which of the following is true about the electrical conductivity of Kylie's two solutions?

A)The solution of sugar water will have a higher conductivity than the solution of salt water.
B) Pure water will have a higher conductivity than both the sugar water and the salt water.
C) The solution of salt water will have a higher conductivity than the solution of sugar water.
D) The solution of salt water and the solution of sugar water will have the exact same conductivity.

Answer 1

C.  because the increased ions in the water will conduct electricity because there are more "willing" ions/electrons to interact
