Alka Seltzer Experiment

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.

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.

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

Prostaglandins are a type of hormone to deal with injury by causing pain and swelling, therefore after consuming alka seltzer the individual feels less pain. When water reacts with sodium hydrogen carbonate and citric acid, an antacid

Some factors that influence the speed of a chemical reaction are: (1) surface area of starting reactants; (2) concentration of reactants; (3) temperatures. The particle theory states that a solute dissolved takes place at the surface of the solvent and the larger the surface area of the particle the longer it will take to dissolve. The smaller the area the faster it will

When adding detergent to water, it sinks to the bottom of the beaker. When mixing them together, the detergent dissolves in the water. This shows once again, that water dissolves most substances, except

Alka Seltzer massively increased their sales by switching to recommending two tablets on their packaging and depicting two tablets dropping into a glass of water in every commercial. This was further reinforced by the creation of the "plop plop fizz fizz" jingle. A similar dramatic increase in sales of shampoo was attributed to the “Lather. Rinse. Repeat.” instruction.

The Constant Variable would be environment and temperature. The Materials needed for the experiment are pencil, paper bag, and stopwatch. There are two components of the procedures section, as there was a pre-lab activity, and the actual experiment. For the pre-lab activity, there was one group member who would breathe into the bag for three minutes, while another group member times thirty-second intervals. The other two group members would observe the

The control group for the experiment was the dialysis bag and potato cores that were immersed in distilled water. Because the experiment was based on the change in molarities, distilled water was a good control because distilled water is pure and has no concentration of any solution. The experimental groups for this experiment were the dialysis bag and the potato

To accurately determine this, each trial will have recorded dependent and independent variables, constants and a control. The hypothesis being researched, indicates higher temperatures allow for a rapid rate of dissolution. In this particular case with someone needing Alka Seltzer, they will feel better faster if they use hot water to dissolve the medicine before

The new mixture that was created was a chemical change because it changed the substance and it now has new

The control group contains 200mL of water, 28.6cm by 17.8cm size of paper towel, the amount of folds to the paper towel, same cup used to put paper towel in, ten seconds to soak paper towel in water, ten seconds to take paper towel out and let it get drip off excess water, and a graduated cylinder used to measure amount of water. On the other hand, the experimental group includes all the same components of the control group, but it adds the factor of changing the paper towel brand. The controlled variable has all the same aspects as the control group and the manipulated variable is the change in paper towel brand. After the procedure finishes, the responding variable represents the amount of water the paper towel absorbs, which is measured using the graduated cylinder. To start off the procedure, the experimenters must first grab the Kirkland paper towel and rip off a 28.6cm by 17.8cm section, which is its given measurements for each piece of paper towel.

In this experiment, there are several factors that can affect

Matter is constantly being changed and converted into different forms of matter; how we identify these changes is a major key to success in Chemistry. The changes in materials can be classified into two categories: Physical and Chemical. During the “Wattsamatta U?” lab, we delved into these changes and discovered some interesting results. Watching a smoothie being mixed, a pot of water boil, or, as we did in a mini-lab about water, watch ice melt, all represent physical changes.

In the experiment there were 4 different test groups: the control (tap water in tap water), 20% fructose in tap water, 40% fructose in tap water, and tap water in 20% fructose.
