Why is sugar water NOT a good conductor of current? Sugar water contains no electrons; therefore, it is not an electrolyte solution that can conduct electricity. Sugar water contains no ions; therefore, it is not an electrolyte solution that can conduct electricity. Sugar water contains many ions; therefore, it is not an electrolyte solution that can conduct electricity. Sugar water contains only a few ions; therefore, it is not an electrolyte solution that can conduct electricity.
The Correct Answer and Explanation is:
he correct answer is: Sugar water contains no ions; therefore, it is not an electrolyte solution that can conduct electricity.
When an electrical current passes through a solution, it requires the presence of charged particles, called ions, which are able to move and carry the charge. These ions can either be positive (cations) or negative (anions). In the case of ionic compounds like table salt (NaCl), when dissolved in water, they dissociate into their respective ions (Na+ and Cl−), making the solution conductive to electricity.
Sugar (sucrose), however, does not dissociate into ions when it dissolves in water. Instead, sugar molecules remain intact as neutral molecules in the solution. As a result, there are no free-moving ions in sugar water to carry the electric charge. This absence of ions means that sugar water is a poor conductor of electricity.
In contrast, ionic compounds like sodium chloride or potassium chloride, when dissolved in water, dissociate into ions that can move freely through the solution. This movement of ions allows for the conduction of electricity. This is why solutions of salts, acids, and bases are typically good conductors of electricity, while solutions of non-electrolytes like sugar are not.
Sugar molecules are covalently bonded, which means they share electrons but do not produce charged particles (ions) in solution. Therefore, despite the fact that water itself is a good conductor due to its polar nature, the lack of ions in a sugar solution prevents it from conducting electricity.
In summary, the key point is that for a solution to conduct electricity, it needs to contain free ions. Since sugar does not dissociate into ions when dissolved in water, sugar water is not a good conductor of electricity.
