Explain How To Change The Solubility Of Solute

452 Words2 Pages

Did you know you can turn sodium acetate into “hot ice”? It is exactly what happens within a chemical heating pack! Inside that pack, along with water, is a solution that has more sodium acetate that can normally be dissolved at room temperature. Sodium acetate is the sodium salt of acetic acid. This solution is called a saturated solution because it contains the maximum amount of sodium acetate that can be dissolved without heating the solution (1).
What is in a solution is a solute, which is the component in a solution, dissolved in the solvent. The solute is the element that is going to be dissolved. The solvent is the liquid in which a solute is dissolved to form a solution. The solvent is the element that is going to dissolve the solute. A solution can become supersaturated if you add more solute to it while the temperature is being increased. When a liquid is heated up, the molecules and …show more content…

Because salt can be dissolved in water, it is said to have high solubility. Sodium acetate also dissolves very easily in water, especially in warm water, so it has high solubility too(1). There are 2 ways to change the solubility of a solution. One way to change it is to raise the temperature because at higher temperatures most solids are extra soluble. The increase of temperature has 2 effects on almost all solutes that are solid. They dissolve more quickly, and a greater amount of the solution dissolves.
The other way to change the solubility, is when the solution is a gas, is to change the pressure. At high pressure the gas solubility in a liquid solvent increases(1). However, for gases. the opposite is true. A rise in temperature makes a gas less soluble in water. For example, when you boil water as it reaches its boiling point, any air that has been dissolved in the water comes out of the solution in

I always knew heat caused things to dissolve faster, similar to how things melt faster the higher the temperature gets above their melting point. I included an extra reactant in my second experiment because I was interested in seeing how that would affect the

Problem: How does the temperature of water used to dissolve an Alka-Seltzer tablet affect the amount of time it would take for the tablet to completely dissolve? An Alka-Seltzer tablet is a medicine tablet made with baking soda used as a pain reliever for “headaches, body aches, pain, heartburn, acid indigestion, and sour stomach” (Alka-Seltzer Tablets). It is put into water, left to dissolve and then consumed. When an Alka-Seltzer tablet is dropped into h20, a chemical reaction immediately takes place and produces bubbles made out of carbon dioxide as a product of the collision (Olson 2). When in its original powder (dry) form, the Alka-Seltzer’s two main ingredients: citric acid and sodium bicarbonate are just there and not reacting to each

”(Factors that affect the boiling point of water.) Overall there are many ways that water 's boiling point can be affected by outside forces, but the focus will be on alkaseltzer tablets and how they influence water 's boiling point. The active ingredients in the alka seltzer tablet are “As the tablets dissolve, the sodium bicarbonate splits apart to form sodium and bicarbonate ions. The bicarbonate ions react with hydrogen ions from the citric acid to form carbon dioxide gas (and water). This is how the bubbles are made.

These increases in kinetic energy then result in an increased movement of both oxygen molecules and water molecules, which causes intermolecular forces to break. This braking of inter – molecular forces allows oxygen to escape into the air which results in a lower saturation. Decreases in temperature result in minimal movement between the molecules, keep the saturation level at a high rate. Past results indicated water temperatures of 23.1 degrees Celsius to 22.9 degrees Celsius, whereas current results show water temperatures of 27.1 degrees Celsius. As solubility changes with fluctuations in temperature, colder water temperatures have higher saturation levels than warmer water temperatures, hence why past results have higher saturation levels.

“Duckweed Recap” The duckweed lab was done to see the effects of road salt on the production of duckweed fronds. The purpose of this lab was to see if the salt concentration significantly affected the growth of the duckweed fronds. We had five different glass jar, one being a control with no salt in the water solution and four jars with different amounts of salt water concentrations and five ml of miracle grow in them. We started the experiment by putting four healthy and green duckweed plants with two fronds on each in every jar.

When temperature is increased, the amount of obtainable energy increases; meaning that particles will move at faster pace at a higher temperature. Thus rate at which molecules diffuse will progressively speed up as the temperature increases. However if temperature of solution is decreased the rate of osmosis will decrease and rate at which molecules diffuse will be significantly less than that of higher

A liquid will boil at the same temperature, and many different liquids have boiling points that are much different from one another. This fact can be used not only to distinguish/identify liquids, but also to separate liquids in a mixture. Though boiling point is constant according to substance, boiling point and air pressure vary directly. This means that boiling point is lower at high altitudes than at sea

A boiling point of a substance is dependent on the temperature at which the substance can change its matter, such as liquid to gas. The molecules present in liquid are tightly compressed together, though they are still moving and colliding. If the liquid is heated, there is a rise in temperature which generates vibrations throughout the liquid, resulting in more collisions between molecules (Helmenstine, 2017). Once the collisions between the molecules become quite intense and rapid, boiling starts to take place. There are molecules that are so powerful, they break through the attraction forces that keep the molecules together, this is called intermolecular forces (Ophardt, 2013).

The Problem: How does temperature affect the dissolving time of an antacid tablet? Antacid tablets are medicines that help neutralize the acid in your stomach. Antacid tablets are made of numerous numbers of components, such as sodium bicarbonate (baking powder), magnesium hydroxide, critic acid, and many others. When Antacid tablets are placed in water, they undergo a chemical reaction, where the sodium bicarbonate breaks apart to make sodium and bicarbonate ions. When the bicarbonate ions collide with hydrogen ions, it produces carbonic acid.

The boiling point of the solution will be higher than that of the pure solvent itself. The boiling point of a liquid is the temperature at which its vapor pressure is to equal the atmospheric pressure. When a solute is added there are less solvent molecules near the surface and the solvent’s vapor pressure will decrease, so the vapor pressure of the solution will be less than that of the solvent. For the vapor pressure to reach the atmospheric pressure, a higher temperature must be reached, which means the boiling point is elevated. According to this theory, adding salt to water would make the boiling point higher, and make it harder to reach the boiling point.

Introduction Solubility is a chemical property that is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called saturated solution. For example when a sample of sodium chloride solution in water is heated the behavior of the reaction is endothermic obstructing exothermic behavior. Another relationship that can be said about solubility is that the solubility of a solid substance increases as the temperature increases. The solubility of solutes is dependent on temperature.
