Does freezing increase salinity

Web1. As each cup was partially frozen, the temperature (T) was lower in the salty water. That's because salt water freezes at a lower T, as we've explained in other answers on this site. T doesn't drop much below the freezing T until all the water is frozen. So what your son noticed was the well-established fact that salt lowers the freezing T. 2. WebThe salt content in the water lowers its freezing temperature by 32°F (17.8°C)! This is a general phenomenon too – dissolving a small amount of any solid in any liquid will decrease its freezing point and increase its boiling point, regardless of what the solid and liquid are. These effects are called the colligative properties of solutions.
