Water dissolves salt by dissociating the ions in salt from each other. Because water is a polar molecule, each of its ends holds a slight positive or negative electrical charge. These ends attract the positive and negati... More »

Salt does dissolve in water. Salt, chemically called sodium chloride, is made up of ionic bonds between sodium and chlorine ions. In a polar solvent such as water, the ions dissociate from one another and become surround... More »

A burning candle is an example of a chemical change because the paraffin wax, which is a hydrocarbon, undergoes a chemical reaction with oxygen to form water and carbon dioxide gas. Because the chemical structure of the ... More »

Gasoline burning is an example of a chemical change, because this process produces water vapor and carbon dioxide. For something to be categorized as a chemical change, it must form new chemical substances. It also entai... More »

Sugar dissolves in water faster than salt due to its different chemical properties. Both substances are similarly sized hard crystals, but their molecular and bonding structures are different, and they react differently ... More »

Vinegar does not dissolve in water. When an element or substance dissolves in water, it is considered soluble. Substances that do not dissolve are insoluble. More »
