Impurities tend to increase the boiling point and lower the freezing point.
in a way boiling point of salty water > boiling point of fresh water
freezing properties of salty water < freezing properties of fresh water
melting properties of salty water < melting properties of fresh water
.Salt water, contains NaCl, which ionizes into Na and Cl ions. when ions are added to a solvent, such as water, they tend to increase the boiling point and lower the melting point.
Impurities lower the freezing point of a solution and raise the boiling point, a phenomenon known as freezing point depression and boiling point elevation. This occurs because impurities disrupt the crystal structure formed during freezing and reduce the vapor pressure during boiling, requiring higher or lower temperatures for the phase change to occur.

What is the effect of mineral impurities of the upper and lower fixed point of a mercury-in-glass thermometer?
Mineral impurities in the upper fixed point of a mercury-in-glass thermometer can lead to an increase in the boiling point of the liquid, affecting the accuracy of high temperature measurements. Impurities in the lower fixed point can similarly impact the freezing point, affecting the accuracy of low temperature readings. Regular calibration and cleaning can help mitigate these effects.
What are boiling point and freezing point examples of?
Boiling point and freezing point are examples of physical properties of substances. Boiling point is the temperature at which a substance changes from a liquid to a gas, while freezing point is the temperature at which a substance changes from a liquid to a solid.
What is the freezing point and boiling point of water using the Kelvin scale?
The freezing point of water is 273.15 K and the boiling point is 373.15 K on the Kelvin scale.
What is the boiling and freezing point of the Fahrenheit scale?
The boiling point of water on the Fahrenheit scale is 212 degrees, and the freezing point is 32 degrees.
Which Kelvin temperature represents respectively the normal freezing point and the normal boiling point of water?
The normal freezing point of water is 273.15 Kelvin, while the normal boiling point of water is 373.15 Kelvin.
What is the effect of impurities on the melting point of ice and the boiling point of water?
The freezing point of water decreases when the number of dissolved molecules (or better particles) in the solvent increases. This is called freezing point depression and you can easily find the relation between the quantity of particles dissolved and the freezing point on Wikipedia.
What are the effect of impurities on the freezing point of water?
Impurities in water lower its freezing point and raise its boiling point. This occurs because impurities disrupt the formation of ice crystals, requiring a lower temperature to overcome these disruptions and freeze the water.
Will there be effect on melting or boiling point of a substance if another substance is added to it?
Yes, impurities have important effects on the melting and boiling point of materials.
What is the effect of decreased pressure on boiling point and freezing point of water?
Decreased pressure lowers the boiling point of water because it reduces the pressure exerted on the liquid, allowing the water molecules to escape into the vapor phase more easily. However, decreased pressure has a less significant effect on the freezing point of water compared to the boiling point, as freezing point is more influenced by the presence of impurities in the water.
How does frozen pure water behave?
Pure water has a freezing temperature of 0 degrees and a boiling temperature of 100 degrees, unlike tap water which has impurities that can alter it's freezing and boiling point
Why is it better to say the boiling point and freezing point of pure water?
It's more accurate to specify "boiling point" and "freezing point" to avoid confusion, as the definition of the terms can vary. For water, the boiling point is 100 degrees Celsius and the freezing point is 0 degrees Celsius at standard atmospheric pressure.
How would the clarity of water affect its boiling point?
Clarity is not directly related to boiling point, but it is indirectly related. Lack of clarity would indicate impurities in the water, and in general, impurities will result in a higher boiling point. But different impurities have different effects, so we cannot make any firm prediction based on a reduction in clarity.
Is the melting point of impure water lower or higher than freezing point?
The melting point of impure water is lower than the freezing point. Impurities disrupt the crystalline structure of water, making it harder for the water molecules to align and freeze. This results in the impure water needing to be cooled to a lower temperature before it freezes.
What is the effect of mineral impurities of the upper and lower fixed point of a mercury-in-glass thermometer?
Mineral impurities in the upper fixed point of a mercury-in-glass thermometer can lead to an increase in the boiling point of the liquid, affecting the accuracy of high temperature measurements. Impurities in the lower fixed point can similarly impact the freezing point, affecting the accuracy of low temperature readings. Regular calibration and cleaning can help mitigate these effects.
What effects do solutes have on a solvent's freezing and boiling boints?
Adding solutes to a solvent lowers its freezing point and elevates its boiling point. This phenomenon is known as freezing-point depression and boiling-point elevation. The presence of solutes disrupts the solvent's ability to form organized solid structures during freezing and reduces its vapor pressure, resulting in these changes.
How is the melting point of asolid and boiling point of a liquidaffected when impurities are added to the substances?
Adding impurities lowers the melting point and raises the boiling point.
What is the antonym for boiling point?
Freezing point.
