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?

Respuesta :

Sugar is an organic compound and does not form ions in solution. Salt is mostly sodium chloride and forms negative Cl ions in solution and positive Na ions. These ions affect electrical conductivity making salt solution a good conductor of electricity. Pure water is not a good conductor of electricity, but an impurity such as salt increases its conductivity. Sugar solution does not enhance water’s electrical conductivity.
