Rate Of Dissolving Lab Report
The topic is The Effect of Temperature on the Rate of Dissolving. In this experiment, the scientist will research how the temperature of water will affect the rate of dissolving of different chemical solutes. The independent variable in this experiment are the different types of solutes used and the different temperatures the solvent will be adjusted to, and the dependent variable is the amount of weight of the solvent after the solute has dissolved in it. The constants are the same cups used to keep the water, the same amount of the solute used, same type of water, and the same type of teaspoons. The control variable is water with no chemical/solute added. To find out how different temperatures affect the rate of solubility, it is necessary

Solubility is the property, or ability of a substance to dissolve in a solvent, and the solubility can be affected by the different physical or chemical properties of either the solute or the solvent, such as temperature or pH value. The extent of solubility can range from infinitely soluble, also can be fully miscible, or from poorly soluble, such as silver chloride with water (Clugston and Fleming, 2000). A solute is when in a solution, the substance that is being dissolved. A solvent is the substance in which the solute is being dissolved in. Examples of solutes can be such as salt, oxygen and baking soda and a very common example of a solvent is water. A solution (also known as homogenous mixture) is defined as "a liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes." (IUPAC, 1997) Although many may not realize, there is a great number of examples of solutions in our lives. For example, the air we breathe in Earth is a solution; it is a mixture of different elements and compounds: carbon, nitrogen, carbon dioxide and many more. Another example of a solution is also jewelry. It is an alloy, or made up of metals, so if a piece of jewelry is bronze, it also means it is composed of copper and
