To generalize: Dissolving an ionic compound is a chemical change. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. And contrast this with the dissolution of salt in water, in which strong electrostatic bonds between ions in the solid are broken, and new substances, i.e. Allowing the water to evaporate will return the salt to a solid state. Color. ALL changes of state are physical changes. 30 seconds . Examples of chemical changes are burning, cooking, rusting, and rotting. Why is sugar dissolving in water not a chemical reaction? The salt may be regained by boiling off the water, leaving the salt behind. Some materials react with water (chemical reaction) to make a new material. In a physical change no new substance is formed. Is water melting a physical or chemical change? Bubbling can be the indication for both chemical or physical change. Concept introduction: In the physical change, the rearrangement of molecules takes place, but their composition remains the same. ... Water can change in two different ways.
