Substances (solutes) are added to water to prevent it from freezing, not to prevent it from melting. Nothing added to ice will raise its melting point above 0°C.
However, anything that insulates ice from external heat will keep it frozen longer. This includes blankets, thermos bottles, or the walls of a freezer.

What effect does sugar have on ice?
yes but not to the same extent. solutes prevent ice formation by lowering the melting point of water. sugar water does have a lower melting point than pure water but it is not as effective as simpler salts because it is less soluble. (conc. of solutes is related to the melting point)
How much ice melting due to global warming?

When pressure on a piece ice is increased its melting point will be?
The melting point of ice actually DECREASES with an INCREASE in pressure.
What do you call it when you change ice to water?
The change from ice to water is a physical change defined as melting, this reaction occurs when ice exceeds a temperature of 32 degrees Fahrenheit (0 degrees Celsius.)
What would best prevent ice from melting plastic or steel?

How do you prevent ice from melting?
Simple. You keep ice in dry ice. But be careful not to eat dry ice!
Is ice melting in tea a chemical reaction?
a chemical reaction transforms a substance into another. in this case, the melting ice would only add more water to your tea, which is already composed primarily of water, infused with tea (leaves). ice melting is only changes the state of the substance--the substance itself does not change!
Why does fabric prevent ice from melting?
because its special gus
Why does salt prevent ice from forming on sidewalk?
salt lowers ice's melting point
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?
A transparent crystalline substance is found to be rather soft and have a low melting point what type of solid is this substance?
ICE
Melting of ice chemical or physical change?
Melting ice is a physical change, because there is no new substance formed. The only thing that changes is the state of matter.
How do you make a insulator that can not make ice melt?
to make an insulator prevent ice from not melting is to use tinfoil and dirt.
Who has higher melting point Pure or Impure Substance?
The melting point of an impure compound is almost *always* lower than that of a pure compound.
What is a hypothesis for what is the best way to keep an ice cube from melting?
One way to keep an ice cube from melting away is if you keep it in ice water.
