As they move faster, they come into contact with the sugar more often, causing it to dissolve faster. Which solvent dissolves the sugar most quickly? We know that the dissolution of a solid by water depends upon the collisions that occur between the solvent molecules and the particles in the solid crystal. If you add more sugar than this, the extra sugar won't dissolve. Notice how the positive areas of the water molecules (near the hydrogen atoms, white) are attracted to the negative area near the oxygen atoms (red) on the sucrose molecules. - Stir the solvent. Legal. In water molecules, their arrangement is in a polar way as oxygen has a negative charge and hydrogen has a positive electrical charge. Tea usually has to be stirredfor a while to get all the sugar dissolved. Based on my results I learned that the amount of water and salt or baking soda might affect which dissolves better. Anything that can be done to increase the frequency of those collisions and/or to give those collisions more energy will increase the rate of dissolution.

We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. 2) We can make the solute dissolve faster by stirring the mixture. Sugar dissolves well in water because water is very polar and interacts with the polar areas of sucrose. There's likely no visible sign of the sugar. For a sugar molecule to leave the crystal and go out into the liquid water it has to pick up some energy, because that raises the total energy of the sugar and liquid. The solute is placed in the solvent and the concentrated solute slowly breaks into pieces. When water is heated, the molecules gain energy and, thus, move faster.

That's because the sugar molecules have split up and spread throughout the glass. Solvent=Water. If it is not stirred, then the water right at the surface of the solute becomes saturated with dissolved sugar molecules, meaning that it is more difficult for additional solute to dissolve. Answer: Stirring, or agitation helps to disperse the particles of sugar throughout the water, which is another way of increasing the surface area of the sugar and accelerating the time it takes to dissolve. Most solids dissolve better in warm water than in cold water. The stirring allows fresh solvent molecules to continually be in contact with the solute. But acetic acid reacts only with certain kinds of substancesand sugar isnt one of them. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.
