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 kylies two solutions?\n○a. the solution of salt water will have a higher conductivity than the solution of sugar water.\n○b. pure water will have a higher conductivity than both the sugar water and the salt water.\n○c. the solution of salt water and the solution of sugar water will have the exact same conductivity.\n○d. the solution of sugar water will have a higher conductivity than the solution of salt water.

Answer

Brief Explanations:

Electrical conductivity in solutions is due to the presence of ions. Salt (sodium - chloride) dissociates into ions in water, increasing the number of charge - carriers. Sugar does not dissociate into ions in water, so it does not contribute to conductivity. Pure water has very few ions and low conductivity. Thus, salt water with more ions has higher conductivity.

Answer:

A. The solution of salt water will have a higher conductivity than the solution of sugar water.
