don't know look in your science book
Firstly, pure salt is white and it becomes colourless when dissolved in water. Secondly, solid salt is a non-conductor of electricity, whereas the solution is an electrolyte and conducts well.
Solubility is considered a physical process.
will change the boiling and freezing point of the water
The water becomes a bit opaque and translucent
It is a physical CHANGE, not property. A property of matter is something like inertia.
For example after phase changes.
The chemical composition of sugar remains the same when dissolved in water. Only the physical state of sugar changes, from solid to liquid. The total amount of matter in the system (sugar + water) also remains constant.
It is a physical change: water changes from gas to solid.
The transition from solid to liquid is a state change. Its ability to flow changes.
The boiling point is a physical property of a substance. It is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure, causing the liquid to change into a gas phase.
It is a physical change because when salt is added to water,it is dissolved in it which only changes its physical appearance.
The physical properties of water can change when a compound is dissolved in water. The dissolved compound will determine which properties change. Some will change the surface tension, others will change the pH. Many changes are possible.
