From what I have been able to figure out, the primary forces of attraction between both water and alcohol molecules is the hydrogen bond, which is largely responsible in each for the high boiling point. Each have London dipole-dipole reactions that are also involved. Perhaps of their similarities, alcohol and water mix well.
Sugar becomes what is know as aqueous( dissolved in solution with the water) this is the process of water molecules breaking and surrounding ions in he sugar so for each sugar molecule several water molecules will be bonded to it thus why if you put enough sugar into water it cant dissolve all of it as there are not enough water molecules to surround the sugar.
The membrane is permeable to water but not to sugar.
A homogeneous mixture
Yes, hot water can generally hold more sugar than cold water due to the increased solubility of sugar at higher temperatures. When water is heated, the molecules move more rapidly, creating more space for sugar molecules to dissolve. However, this relationship is not linear and can vary depending on factors such as the type of sugar and the specific conditions of the solution.
It doesn't really disappear, it dissociates. Water is a solvent, and causes tons of stuff to separate, including sugar. Table sugar is not a single molecule (ie. glucose), but instead is a combination of carbon, hydrogen and oxygen (C12H22O11), and simply put, those pieces come apart in water giving the appearance of disappearing. (But they are actually only changing forms.)
When a solid such as a sugar cube dissolves in water, the molecules of the sugar cube spread out and become surrounded by water molecules. The water molecules interact with the sugar molecules and weaken their bonds, causing the sugar molecules to separate and disperse throughout the water, resulting in a homogeneous mixture.
Sugar and water both are ionic compounds. Due to this sugar dissolve into water further sugar molecules breaks into small molecules in presence of water molecules.
The concentration of water molecules is higher in pure water compared to sugar water. Sugar water has sugar molecules dissolved in it, which decreases the concentration of water molecules relative to pure water.
Sugar water is a solution because the sugar molecules do not chemically bond to the water molecules.
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.
When a sugar cube is placed in water, the water molecules surround the sugar molecules due to their polarity. The water molecules break the bonds holding the sugar molecules together, causing them to separate and disperse throughout the water. This process is called dissolution, where the sugar molecules become evenly distributed in the water, forming a sugar solution.
Large groups of sugar molecules break apart in water due to the solvent properties of water. The polar nature of water molecules interacts with the polar components of sugar molecules, causing them to dissolve and separate into individual sugar molecules. This process is known as hydration.
Change phaze
When granulated sugar and water come in contact, the water molecules surround the individual sugar molecules, and the sugar molecules go into solution. You end up with an aqueous solution of sugar.
The "cube" disappears but the "sugar" doesn't. When placed in water the sugar dissolves. Essentially the sugar molecules break off from the solid and hide among the water molecules. If the water were to be removed by evaporation the sugar would precipitate out. if done carefully large sugar crystals will grow in the evaporating solution. The sugar cube will not reform as this is an artificial construct.
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.
It's a solution, since the sugar is dissolved in water.
