Dissolution is what happens when the bonds that hold a powder together break down into a medium. Dissolution can happen under many conditions and temperatures. The question is, “Which temperature dissolves the powder the quickest and easiest?” In order for dissolution to happen, you must have both a solute and a solvent. A solute is something that can be dissolved into a solvent, a medium into which something can be dissolved. The bonds holding the solute together must first be dissolved and broken down before the solute and the solvent can form its own bonds. When the solute and solvent combine, a solution is formed. Specific solvents can only hold so much dissolved solute, which when overfilled can cause clumps to form in the solvent. “At some point the solution …show more content…
I will be using my experiment to answer my question. My hypothesis for this experiment is that the hot water will dissolve the powder the fastest. For this experiment, I will need 1. Three clear cups 2. Cold, room temperature, and hot water 3. Kool-Aid powder 4. A white piece of paper With these items, I will be conducting the following experiment. 1. I will have three cups of water each with cold, room temperature, and hot water respectively. 2. I will set the said cups on a white piece of paper, in order to be able to tell the exact moment that the Kool-Aid powder is completely dissolved. 3. I will write cold room temperature, and hot in front of the cups respectively in order to be able to identify the cups. 4. I will get three tablespoons of Kool-Aid powder and pour one tablespoon into each cup. 5. I will then wait to see which water temperature dissolves the powder completely first. 6. I will then repeat these steps one more time in order to make sure that the results are accurate. With these results, I will be able to accurately answer the question,” Which temperature dissolves the powder the quickest and
Our original question was what is the effect of different types of water on an Alka Seltzer tablet? What we were measuring was which type of water will make the tablet dissolve the quickest. Our hypothesis was the salt water would dissolve it the fastest, then the pond the second, and tap would take the longest. The results ended up being that the tap water would dissolve the tablet the fastest, then the pond water, and the the salt last. Our three controls are the amount of salt, the amount of water, and the size of the tablet.
A hot plate was placed under the ring stand. 50 mL of 3.0 M NaOH in a 250 mL beaker and a stir bar was placed in the beaker. The beaker with NaOH was placed on the hot plate and 3.75 grams of NaAlO2*5H2O was placed in the beaker. The temperature probe was placed in the beaker with the solution, not touching the bottom of the beaker. The solution was heated and stirred till the solution dissolved.
Materials 1. Clean and dry 250 mL beaker. 2. Determine the mass of 2 Alka-Seltzer® tablets. 3.
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
During one experiment the results were, they found out that the higher the temperature of the water the faster the molecules will move and the lower the temperature the slower the molecules move. The molecules are what are make the alka-seltzer dissolve. So if they move slower the alka-seltzer dissolves slower, same as if the molecules move faster than the alka-seltzer will dissolve faster. Also according to a state science fair the results were that it took 19.53 seconds for the alka-seltzer to dissolve in hot water, 36.15 seconds for the alka-seltzer to dissolve in the warm water, and 96.17 seconds (1 minute and 36.17 seconds) for the alka-seltzer to dissolve in cold water. The alka-seltzer dropped in the cold water proved to dissolve the
As much was conducted throughout this lab, the projected completion of this lab displays that ultimately, the higher the temperature of the water, the faster the dissolving rate of the Alka-Seltzer is. In other words, the hotter the water temperature the quicker the tablet dissolves within the water in regards to the amount of time it took to dissolve. Furthermore, this experiment helps to explain that, if water is taken at a higher temperature and Alka-Seltzer is placed within the water, the Alka-Seltzer will take less time to dissolve because the higher temperatures cause the tablet to melt at a quicker rate. This compares to when Alka-Seltzer is placed in colder temperatures, where instead it takes more time to dissolve, because the lower
In the second portion of this experiment we will keep the temperature constant and divide the ½ tablet of Alka- Seltzer into 2 pieces ,3 pieces and an unbroken ½ tablet. It is my belief that Alka-Seltzer
For this experiment, the materials needed include an
Introduction: In this assignment, I will be doing two experimentations on examining the impact of temperature on the Alka-Seltzer’s response time. The first experimentation that I will be doing involves some water that is room temperature. The second experimentation that I will be doing involves some water that is very hot. If I want to be able to figure out the impact of the temperature on water, I will have to document the time it will take for the Alka-Seltzer to go into solution.
In one of the experiments, the experimenter uses coke, lemonade, water, red party cups, and a thermometer. They put a measuring cup of each liquid into cups and they freeze them at 32 degrees Fahrenheit. The water froze the quickest, freezing within 2 hours. The Coke came second at 2 hours and 15 minutes. The lemonade froze the slowest at 2 hours and 35 minutes.
Like how the temperature affected how long it took for the tablet to react to the water, if there is only one drop water used to dissolve the whole tablet, the time it takes for the whole tablet to react to the water and start to dissolve will be
Also, although this likely served no contribution in disheveling the results, using a stirrer of the same material to ensure the separate testing of each substance will be as uniform as
For any solute to dissolve in a solvent, the molecules must be able to interact with each other. Water is a polar solvent as it carries positively charged hydrogen atoms at one end and
Solutes and solvents can be in the form of a solid, liquid, or gas form to be considered a component in the reaction. Depending on the form a solute is present, the solubility of the solute can differ. Other factors can play a substantial role in how or when a solute will dissolve in a solvent. Temperature is usually the biggest factor to consider when solubility is being recognized. A solute or solvents temperature can effect the kind of reaction that will take place, and effect the solubility of the solute.
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.
