The rate of dissolving depends on the surface area (solute in solid state), temperature and amount of stirring. Solutes successfully dissolve into solvents when solute-solvent bonds are stronger than either solute-solute bonds or solvent-solvent bonds. concentration A sugar cube is tightly compacted granulated sugar, meaning it has less surface area exposed to the solvent. 91 people found it helpful. So the hotter the water, the easier it is for a sugar molecule to pick up enough energy to break away from the crystal. Powdered sugar will dissolve in water with enough heat, just like granulated sugar. This is because sugar is soluble in liquid water at all temperatures at standard pressure. . Crushing it has really no affect on solubility because we have not stirred it at all. Salt is an example ofa solute that changes a little when the temperature of water rises. For a higher sugar concentration, pour just enough hot water over the sugar to make a runny, pudding-like consistency. The sugar cube would eventually dissolve because random motions of the water molecules would bring enough fresh solvent into contact with the sugar, but the process would take much longer. It is generally used in making delicate or smooth desserts, such as mousse or puddings. solution Oils, fats, and certain organic solvents do not dissolve in water because they are hydrophobic. So, feel free to use this information and benefit from expert answers to the questions you are interested in! The rate at which a solute dissolves depends upon the size of the solute particles. The substance that does the dissolvingin this case, the wateris the solvent. This means that a greater amount of zinc chloride can be dissolved in the same amount of water than lead II chloride .
