What happens to the freezing temperature of a solution of table salt in water as the solution becomes more concentrated?
As concentration of a solute (like table salt) in a solvent increases, the freezing point of water lowers. The vapor pressure also decreases, and the boiling point increases. These are known as water's colligative properties.
How does salt affect the melting and freezing point of water?
Salt decreases the freezing point of water and increases the boiling point of water.
Effects of impurities and pressure on melting point of water?
melting point decreases with pressure and increases with impurities (like saw dust). boiling point increases with impurities and also increases with pressure.
How does the melting point of water change as pressure increases from1atm?
Decreases
Why does the freezing point decrease when naphthalene is added in camphor?
When adding a solute to a solvent, the freezing point decreases and is also known as freezing-point depression. Hence when naphthalene is added to camphor the freezing point decreases.

What occurs when NaCl is added to water?
The boiling point of the solution increases, and the freezing point of the solution decreases.
Effects of impurities and pressure on melting point of water?
melting point decreases with pressure and increases with impurities (like saw dust). boiling point increases with impurities and also increases with pressure.
How does the melting point of water change as pressure increases from1atm?
Decreases
What decreases with increasing attraction between molecules?
Freezing point raised Boiling point raised etc. As the molecules in the substance is more strongly bonded together and is hard to separate.
Does the boiling point of a liquid decreases increases or stay the same if the intermolecular force increases?
Generally, the boiling point of a liquid increases if the intermolecular force, i.e. pressure, increases.
Why does the freezing point decrease when naphthalene is added in camphor?
When adding a solute to a solvent, the freezing point decreases and is also known as freezing-point depression. Hence when naphthalene is added to camphor the freezing point decreases.
Describe the difference if any there would be between the boiling point of alcohol measured in Houston and in Denver the mile high city?
the boiling point would be lower because pressure decreases as altitude increases. the boiling point would be lower because pressure decreases as altitude increases.
How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
What happens to water when antifreeze is added to it?
The boiling point increases and the freezing point decreases.
What happens to water if the salinity increases?
The heat capacity and freezing point decrease, evaporation slows, and osmotic pressure increases.
