Sugar cubes (and salt, and many other materials) dissolve in water because water is a powerful solvent. Properties of water molecules cause them to break down the crystalline structure of a sugar cube.
Polar MoleculesWater molecules are polar, meaning that one part of the molecule has a slightly positive electric charge, and one part has a slightly negative electric charge. Sucrose molecules also have a part that carries a slight negative charge.
Crystalline BondsThe bonds that hold a sugar cube together in a crystalline structure are fairly weak and rely on the sugar molecules being in contact with each other.
Water Breaks the Crystalline BondsThe attraction between the negatively charged part of the sugar cube and the positively charged part of the surrounding water molecules pulls the sucrose away from the crystalline structure.
Water Surrounds the SucroseThe negatively charged part of the sucrose molecule pulls in water molecules from all directions. They form a shell around the sucrose, preventing it from rejoining the crystalline structure. This layer of water molecules is called the hydration shell.
Removing the WaterWhen the water is removed, through evaporation for example, the sucrose molecules come into contact with each other again and reform their crystalline bonds. They are not changed chemically in any way by the process of absorption.

What is the slowest way to dissolve sugar?
Adding sugar to cold water is the absolute slowest way to dissolve the sugar. If you're wanting to dissolve sugar at a very fast rate, add some sugar crystals in a hot beverage.
Why does a sugar cube give off air bubbles when dissolving in water?
The air bubbles are trapped within the sugar cube and are released as the sugar dissolves in water. These air pockets are a result of the manufacturing process of the sugar cube, where they can get trapped during the compression of the sugar granules.
What happens if you mix water and sugar?
There is no chemical reaction. Most sugars are soluble in water, so the sugar will probably dissolve; dissolved sugars tend to form hemiacetals or hemiketals if they're not already in that configuration.
Does acetone dissolve sugar?
Yes. Wet acetone will disolve sugar because of it's high water content, and although dry acetone will dissolve sugar, it will not do so in the way that wet acetone will.
Salt or sugar what dissolves in ethanol?
No, Salt will not dissolve because the Ethanol is less dense then the salt so in order to make it dissolve u have to have a greater density then a smaller density. Ex. Sugar and water. When you stir it mixes and mixes all of the particles together. And same for the Sugar.
Can a sugar cube dissolve in water?
Yes, a sugar cube can dissolve in water. When placed in water, the sugar cube breaks down into individual sugar molecules due to the interactions between the water molecules and the sugar molecules, causing the sugar cube to disappear into the water.
What chemical makes a sugar cube dissolve?
Water is the chemical that dissolves a sugar cube. The water molecules surround the sugar molecules and break the bonds holding them together, causing the sugar cube to dissolve.
What happens if you drop a sugar cube in warm water and stir?
The sugar cube will dissolve in the warm water as it is soluble. Stirring will help to speed up the dissolving process by increasing the contact between the water and the sugar cube. Eventually, the sugar will completely dissolve in the water, resulting in a sweet solution.
What will have the highest rate of solubility a sugar cube in boiling water a sugar cube in room temperature water a sugar cube in refrigerated water?
solubility generally increases on heating. so sugar cube in boiling water will dissolve fastest.
How can you improve the solubility of a sugar cube in water?
You can improve the solubility of a sugar cube in water by crushing the sugar cube into smaller pieces to increase the surface area exposed to the water, stirring or agitating the solution to help the sugar dissolve faster, and heating the water to increase its ability to dissolve the sugar.
How long would it take to dissolve a sugar cube in hot water?
that depends on the quantity of water and the size of the sugar cube .......if i am correct
Does a sugar cube dissolve in water make a chemical reacattion?
no
How long does it take for a sugar cube to dissolve in one half cup of hot water or and in one half cup of cold water?
The sugar cube in the hot water will dissolve faster because there are more and higher energy collisions between the water molecules and the sugar molecules which will cause the sugar to dissolve faster.
Why would granulated sugar dissolve in water than a sugar cube?
Granulated sugar would dissolve faster because there is more surface area exposed to the water.
Why does a sugar cube dissolve faster in salt water than fresh water?
magic
Why does a sugar cube dissolve in warm water?
In warm water the forces between sugar molecules are weakened.
Why sugar dissolve faster in hot water?
solutionswhen a sugar cube dissolves in water, it becomes a solutionof sugar and water. a solution can be said to be a homegenous mixture of the water and sugar molecules. in order for this to happen, the sugar cube molecules have to become free from each other to mix freely with the water molecules. this requires energy, since the bonds between the molecules in the sugar cube have to be broken. since hot water has more energy than normal water, it is easier for the sugar cube to dissolve.
