Electrolytes form ions in the solution not depending on the nature of the substance. They can be used in different ways such as salt ions covering the vapor of the ice to stop it from evaporating, thus could be used to preserve ice creams. In the choices above, the electrolyte is A: magnesium sulphate (MgSO4). When break down in a solution, magnesium (Mg2) and sulfur (SO4) forms ions. Copper is metal, distilled water is a neutralized solution, and sugar is a compound that cannot form ions due to its structure.
Which of the following substances is an electrolyte? A:magnesium sulphate B:copper C:distilled water D:sugar
