Substances will dissolve in each other if there are strong intermolecular forces between solvent and solute molecules.
The intermolecular forces in water are primarily Hydrogen bonds. These are the result of the dipoles (slight charge) within the molecules themselves. Oxygen attracts the negatively charged electrons in the molecule more readily than hydrogen, so it gains a slight negative charge, while leaving the hydrogen with a slight positive charge. The attraction of the positive dipole on the hydrogen of one water molecule with the negative dipole on the oxygen of another holds the water molecules together as a liquid.
Polar molecules also contain positive and negative dipoles. Sugar contains several O-H bonds, which have a similar distribution of charge to the water molecules. When sugar is added to water, these dipoles are subject to strong attractive forces from the opposite dipoles on the water molecules, causing single sugar molecules to break away from the main body of sugar and dissolve in the water.

Why does sugar dissolve easily in milk at room temperature?
Milk is mostly water, which is very polar. Sugar (sucrose) is also a rather polar molecule. So, polar compounds dissolve readily in polar solvents. That is why sugar easily dissolves in milk.
Is sugar immiscible in water?
No, sugar is soluble in water, which means it can dissolve into water to form a solution. Sugar molecules are polar, allowing them to form bonds with the polar water molecules, resulting in a homogeneous mixture.
What substance dissolves best in water?
Ionic compounds, such as table salt (sodium chloride), generally dissolve best in water due to the attraction between the ions and water molecules. Additionally, polar molecules, like sugar and alcohols, can also dissolve well in water because water is a polar solvent that can easily interact with the polar molecules.
Why does a sugar cube not dissolve in isopropyl alcohol?
Because the particle of the sugar are heavier that the particles of the rubbing alcohol so they tend to stay at the bottom of the container and do not dissolve p.s. I an not sure about this answer but hopefully it helps
What physical property does sugar have that makes it dissolve in water?
A grain of sugar is actually a large collection of sugar molecules (with most of the water eliminated if dry). When the sugar grain is placed in water the sugar molecules are free to separate and drift in the water (without a chemical change to the molecules). Drying the water out again restores the sugar to crystal grains although perhaps much larger. For sugar to dissolve, water must wet it (unlike wax and oils, etc.).
Why urea and sugar are polar?
Urea and sugar are polar molecules because they contain polar covalent bonds due to differences in electronegativity between the atoms involved. This creates regions of partial positive and negative charges within the molecules, making them polar. This polarity allows them to readily interact with water and other polar substances.
Why do small grains dissolve faster in water?
It mostly has to do with the interaction of the water molecules with the solute molecules. Smaller solute particles have an increased surface area with which to interact with the water molecules-hence they dissolve faster...

Why does water dissolve sugar?
Because sugar is a polar molecule, which in other words means it can easily dissolve in polar solvents such as water. Water breaks the bonds between the sugar molecules, it does not break the bonds within the molecule.
What happens sugar is added to water?
The sugar will dissolve in water because sugar is polar and so is water with hydrogen bonds. When attraction happens, the water molecules will separate the sugar molecules and the sugar will be dissolved.
What things dissolves in water?
Polar molecules like sugar and ionic substances like salt will dissolve in water.
Will salt and sugar dissolve in petrol?
Unlike salt and sugar, petrol is a nonpolar substance, meaning that the electrons in its molecules are evenly distributed, rather than concentrated in some areas to make the molecule negatively charged on one side and positively charged on the other, as is the case with polar substances. Polar substances, as well as ionic substances such as salt, tend to dissolve more effectively in other polar substances, such as water, while nonpolar substances tend to dissolve well in nonpolar substances, such as oil. So while salt and sugar dissolve well in water, and oil might dissolve well in petrol, salt and sugar will not dissolve to any great degree in petrol.
What substance dissolves best in water?
Ionic compounds, such as table salt (sodium chloride), generally dissolve best in water due to the attraction between the ions and water molecules. Additionally, polar molecules, like sugar and alcohols, can also dissolve well in water because water is a polar solvent that can easily interact with the polar molecules.
Describe as a series of steps what happens to sugar molecules when they dissolve in water?
When sugar molecules dissolve in water, they are surrounded by water molecules that bond with them. This process breaks the sugar molecules apart, dispersing them evenly throughout the water. As a result, a sugar solution is formed where individual sugar molecules are no longer distinguishable.
What kinds of substances dissolve water?
Powders like sugar, salt, baking soda, etc.
Does sugar dissolve in ethyl acetate?
No, sugar does not dissolve in ethyl acetate because sugar is a polar molecule that is more likely to dissolve in polar solvents like water. Ethyl acetate is a nonpolar solvent and is not capable of dissolving polar substances like sugar.
