Impurities in a liquid raise its melting point. For example, putting SALT on Ice raises the melting point above 32 F. This causes the Ice to melt, because, consequently its FREEZING point has been LOWERED. So, at 32F ice plus salt is just liquid SALTWATER.

How does the addition of impurities to a metal affect its melting point?
generally addition of impurities lowers the melting pointand increases the boiling point
How do you prove that glucose do not raise the melting point of stearic acid?
No, impurities do not raise the melting point of Stearic Acid, they decrease it. All impurities decrease the melting point of solids.
Effect of impurities on melting point and melting point?
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
What is melting point of acetamide?
The melting point is influenced by the presence of impurities in the material.
Why is it misleading to identify a solid compound just from a lone melting determination?
Because the melting point can be very similar; also impurities change the value of the melting point.
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.
If a substance is impure what will be the two effects on its melting point compared to the literature value?
the impurities will lower the melting point value.
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.
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.
How does the addition of impurities to a metal affect its melting point?
generally addition of impurities lowers the melting pointand increases the boiling point
What melting point depression?
This is the modification of melting (freezing) point due to impurities in the material.
What is melting point depression?

No, impurities do not raise the melting point of Stearic Acid, they decrease it. All impurities decrease the melting point of solids.
What effect would contaminating the sample with an insoluble impurity have on the melting point?
Soluble impurities (that is, impurities that are included within the crystal matrix) tend to lower the observed melting point and broaden the melting point range. Insoluble impurities have no effect on the melting point. Found from website: http://swc2.hccs.edu/pahlavan/2423L1.pdf
To increase Melting and boiling point of Zinc what is to be done?
To increase MP and BP point of Zinc u should add some impurities in it. The addition of impurities always decreases the melting point .

According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
How can the melting point of water be changed?
by adding impurities the melting point of ice can be increased.... and perhaps can water melt i think the right question suppose to be how can the melting point of ice be changed?
