Technically, they do not melt ice -- it requires heat to do that. But the addition of any solute (dissolved material) to water will lower its freezing point. So adding salt or sugar prevents melting ice from refreezing, or at least not until it gets much colder.
The solute has the effect of blocking molecules attempting to form lattices in the water (ice), so it requires a lower temperature before the same number of water molecules can form crystals.
salt and sugar affect ice because both of them have some kind of acid
It doesn't melt faster but it does melt at a lower temperature. This is because the sugar molecules mix in with the water molecules and prevent them from organizing to form a solid. For more information, look up 'colligative properties,' these are the properties of solutions.
Fresh-water ice will melt faster in salt water than it will in fresh water or in the open air. Ice forms when water molecules are cooled down enough to arrange into solid crystals. Salt will, basically, get between the water molecules and make it harder for them to form crystals.
Hot water, salt can melt an ice cube as well but hot water raises the temperature in the ice cube causing it to go through a phase change referred to as melting thus turning it to a liquid more rapidly than salt could.
yes
Hypothesis: Sprinkle Salt on ice would melt the ice. Null-Hypothesis: Sprinkle Salt do ice do not melt the ice. Theory behind hypothesis: (explain what any why you believe the salt do or interact to melt the ice like if it exert heat from solution) Hypothesis is just write the sentence describe what would you believe in the result and what might be the cause of what is going on. You then design experiment base on your hypothesis.
Salt
Salt, obviously.
Salt will melt first.
For making the ice colder? It wouldn't work at all. The reason you put the salt on the ice is to make it melt; when ice melts it absorbs heat. Sugar won't melt ice.
sugar
SALT DOESNT MELT THE ICE IT JUST LOWERS THE FREEZING POINTWell Salt Does Make Ice Melt Faster :) I made the project and my result were correct SALT melts ice faster :)
salt
Sugar. Salt often slows down the process of melting, so sugar is what would melt it faster.
It doesn't melt faster but it does melt at a lower temperature. This is because the sugar molecules mix in with the water molecules and prevent them from organizing to form a solid. For more information, look up 'colligative properties,' these are the properties of solutions.
The salt will cause the ice to melt faster. the sugar shouldn't have much of a difference.
