We use the term soluable to refer to the capability of a substance to be dissolved – “Sugar is soluable in water.” The resulting mixture is called a solution. The definition of a solution is a homogeneous mixture of two or more substances in a single phase. It is importantto understand that even though a gas may be dissolved into a liquid, once the gas is in solution it is now in the liquid phase. Using the sugar dissolved in water example, the sugar is now in the liquid phase. We call the sugar (the substance being dissolved) the solute, and we call the water (the medium the solute is being dissolved into) the solvent.
Another important part of the solution process is having a general idea if a particular solute will dissolve in a particular solvent. Now that we have a general idea why some substances will dissolve in others, it is important to visualize what happens at the molecular level when a solute is added to a solvent.
Mini-Lab - Determining what happens when a solute is added to a solvent. In this miniinvestigation you will be using food coloring and various amounts of water to help you get a sense of what might be happening on the molecular level when a solute is added to a solvent. You may have had experience using food coloring before while cooking and know about some of its properties. If you don’t, that’s O.K. This mini investigation is for you to explore.
Materials
Assorted beakers
4 Color box of food coloring
Deionized water Stirring rod
Colored pencils
Procedure
Use the beakers, water, and food coloring to explore the effects of adding food coloring to water. You may use any amounts of water and any colors to experiment with. The main question that you are trying to answer is: “What is happening on a molecular level when I add the solute to the solvent?”
What you think is happening at the molecular level when you add the food coloring to the water.
You may repeat the investigation as many times as you want and with any combination of materials.
Food coloring is a liquid. It is a concentrated liquid used to add color to food and beverages. It is typically water-soluble and does not exist in a gaseous state.
Yes, water-soluble supplements can be taken with food. It is generally more important to take fat-soluble supplements with food to aid in their absorption, while water-soluble supplements can be taken with or without food as they dissolve in water.
Copper (II) sulfate and cobalt (II) chloride are examples of soluble salts that are blue in color.
Manganese sulfate is typically a pale pink or light tan color when in solid form. It is highly soluble in water, with a solubility of approximately 700 g/L at 20°C.
Black is the least soluble color, as it reflects all wavelengths of light and absorbs the least amount of light when dissolved in a solution.

The soluble portions of food are absorbed by the small intestine into the bloodstream.
Yes. But this occurs because salt is soluble in water, in which the coloring is dissolved. The color is retained by the salt crystals when they dry.
A color change can indicate that a substance is soluble or insoluble, depending on the specific reaction. For example, some reactions may result in a color change when a soluble compound is formed, while other reactions may cause a color change when an insoluble precipitate is produced. The nature of the reactants and products involved in the reaction will determine whether the color change indicates solubility or insolubility.

none I believe oats (Oatmeal, cheerios) is soluble fiber.
Yes, they are. You can do a chromatogram and find out for yourself. The color that rises to the top faster is the most soluble.

Black is the least soluble color, as it reflects all wavelengths of light and absorbs the least amount of light when dissolved in a solution.
In general, white is considered the least soluble color because it reflects most light and appears colorless. However, the solubility of colors can vary depending on the specific substance and conditions.
Digestion is the breakdown of large food molecules into small, water-soluble food molecules that can be absorbed.
