Answer:
When you add sugar to water, the sugar dissolves in the water to create a homogeneous mixture. The sugar molecules break down into individual molecules, and each molecule becomes surrounded by water molecules. This process is known as dissolution or solvation.
As the sugar dissolves, it raises the total amount of solutes in the water, increasing the solution's concentration. The concentration of the sugar in the water can be measured using various techniques, such as refractometry or titration.
The addition of sugar to water also affects the physical properties of the solution. For example, the boiling point and freezing point of the solution change due to the presence of the sugar molecules. The boiling point of the solution increases, while the freezing point decreases.
Finally, the addition of sugar to water can also affect the taste of the water. The dissolved sugar molecules can make the water taste sweeter, depending on the concentration of sugar in the solution.
