First of all, an alka-seltzer is an a little tablet that helps with multiple pain. For example, alka-seltzer helps with migraines, headaches, sinus headaches, muscle pain, and symptoms of pain. Alka-seltzer contains aspirin, sodium, hydrogen carbonate, citric acid, natural flavors, and artificial flavors. These are just some of the ingredients. When an alka-seltzer dissolves it releases all of the medicine. Alka-seltzer is an easy pain killer. What makes an alka-seltzer dissolve? The formula for an alka-seltzer is 3HCO3−+3H+→3H2O+3CO2. This is what makes it dissolve. Sodium bicarbonate or baking ions react with hydrogen ions then mixes ions with water, carbon dioxide gas which is the fizz. Baking soda and citric acid mixed when dropped in the water, which causes a chemical reaction to happen. There are multiple components that make an alka-seltzer dissolve. …show more content…

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

Alka-Seltzer is a medical drug that works as a pain reliever and an antacid. The pain reliever used is aspirin and the antacid used is baking soda. When sodium bicarbonate dissolves in water it splits apart into sodium and bicarbonate ions. The bicarbonates reacts with hydrogen ions from citric acid to form carbon dioxide gas and water. This is how the bubbles are made.

A buffer solution minimises change in PH of a solution when small amounts of acid or alkali are added to the solution, with an an acidic buffer solutions maintaining a PH<7 (ChemGuide, 2017). It works through an equilibrium, so if the concentration of H+ or OH- are changed, equilibrium will shift to oppose this change and return solution PH to original value. The Alka Seltzer mixture contains an excess amount of the bicarbonate ion which is vital for the buffering action taking place within the solution. This is because the excess bicarbonate ion present, allows the solution to act as a buffer as it’s able to react with small quantities of acids and bases added to the solution, therefore resisting a change in PH by neutralising them.

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.

Introduction Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment.

Alka-Seltzer is something that when it gets put into water it has a chemical reaction because it starts to bubble up and when it starts to bubble up the bubbles are carbon dioxide gas. Chemical reactions start when matter is mixed with other matter, you can recognize new compounds by their color or by their acid levels or how a compound looks, feels, or how it acts. Substances create a solid compound. The chemical reaction also happens from more products and properties. They can have one or more products or properties.

Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌

This is a poster about the density of the plastic of a water bottle, it was a group project with 4 people, including myself. We used scientific method and included all that information on the poster. In the lab, we did 3 trials, each with a different piece of a different brand of water bottle, we made a table, a scatter plot, and a bar graph to organize our data and we also calculated the percent error. The table had trails, volume, mass, and destiny on it, the scatter plot was on mass and volume, and the bar graph was on density and trails, all of this data went into the results section of our poster. After we did the lab, we typed out an introduction, methodology, discussion, and a literature cited.

Isolation of Ecdysterone from Sesuvium portulacastrum As detailed in Figure1, Ecdysterone was isolated from Sesuvium portulacastrum using a sequential extraction process with Chloroform (CHCl3) followed by Methanol (MeOH), after which Alumina column chromatography of MeOH extract was performed. The different fractions were then eluted using varying proportions of CHCl3 and MeOH, resulting in MeOH: CHCl3 (20:80) bioactive fraction. Thin-layer chromatography (TLC) analysis of MeOH: CHCl3 (20:80) fraction was carried out using a solvent system containing MeOH (15%) and Ethyl Acetate (85%).

Joshua Miller 12/18/17 Fermentation Lab report Introduction The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.
