![]() These sugar molecules can then get pulled into the water molecule and dissolve. When these two substances mix, the sugar molecules find themselves being surrounded by two or more water molecules since they are smaller. The polar water molecules have a partially positive capsule surrounding a negatively charged hydrogen atom. Sugar dissolves in water because the sugar molecules are smaller than the polar water molecules. It is also possible to observe what is called “further solvation” by adding more sugar or salt to the already dissolved sugar or salt. This process is known as solvation, which is an electrostatic interaction between molecules. When dissolved, this reaction produces a solution that has properties different from those of the two substances individually such as a change in color and flavor. Sugar dissolves in water because the molecules of sugar react with the molecules of H2O. Furthermore, sugar does not react with the water molecules to form new bonds or break old ones. Carbohydrates are neither acidic nor basic and they do not react with each other. Sugar is classified as a simple carbohydrate because it is made up of only one molecule. Sugar dissolving in water is not, in fact, a chemical change. Is sugar dissolving in water a chemical change? Simple chemical changes, such as the burning of paper, are the most common.Ĭomplex chemical changes usually require more energy and include things like making chocolate milk from powdered cocoa and skim milk, which requires heating up the ingredients with stirring. ![]() Chemical changes can be either simple or complex. A chemical change is when two substances combine to form a new substance.
