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 …show more content…
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

    This project looks at how the temperature of an experiment can affect its reaction time. The purpose of this experiment is to determine if dissolving reactions are affected by waters temperature. I believe that if the H2O temperature increases, then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the experiment. The Manipulated variable will also be the water, since I will be changing its temperature. The Responding the variable will be the timing of how fast or slow the Alka-Seltzer tablet dissolves. And the control is the glass of water that is set at cold tap water.…

    The main purpose of doing this lab is to learn how to interpret solubility graphs and how the temperature does affects the solubility of different substances. There are other objectives of the lab which are learning what are concentrated, diluted, supersaturated, and saturated substances and how can they be identified. The hypothesis of this lab would be that when temperature increases, the amount of salt and copper sulfate that can be added in the water and be dissolved will increase.…

    Introduction: A solution is as a homogeneous mixture containing two or more substances. Reagents are added to solutions to create a chemical reaction or added to see if anything occurs. Reagents can be added to solutions to see if there is a presence of other substances. For example, iodine added to a lead solution. Iodine would be the reagent and would cause a chemical reaction confirming the presence of lead. We use a qualitative chemical analysis to identify elements present in the solutions, in this case, adding a reagent. A quantitative chemical analysis is used to determine the percentage of a substance in the solutions. Solvation is the process of the attraction between…

    Most substances have a specific solubility (amount of solute that dissolves) in water at a given temperature. Solubility is defined as the ability of a substance to dissolve in another substance. Solutions are mixtures containing a solute (substance being dissolved) and a solvent (material that dissolves another substance). Solutes and solvents can be solids, liquids, or gases. The most common solutions, however, have liquid solvents, particularly water.…
